#quantum key distribution

[thatshuffle]

A point-to-point long-distance quantum key distribution (QKD) over a distance of 1,002 km has been achieved by scientists from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), and their collaborators from Tsinghua University, Jinan Institute of Quantum Technology, and Shanghai Institute of Microsystem and Information Technology (SIMIT), CAS. This milestone not only sets a new world record for non-relay QKD but also provides a solution for high-speed intercity quantum communication. The results were published in Physical Review Letters on May 25th.

QKD is based on the principles of quantum mechanics and enables secure key distribution between two remote parties. When combined with the "one-time pad" encryption method, it can achieve the highest level of security for confidential communication. However, the distance of QKD has been limited by factors such as the channel loss and system noise.

The twin-field QKD (TF-QKD) using sending-or-not-sending (SNS) protocol was demonstrated in the experiment, improving the relation between the key rate and channel transmittance from a linear η to its square root η. Therefore, it can achieve a much longer secure distance than traditional QKD protocols.

To achieve long-distance QKD, the research team collaborated with Yangtze Optical Fiber and Cable Joint Stock Limited Company (YOFC) and used ultra-low-loss fiber based on pure silica core technology, which achieved a maximum attenuation of 0.16 dB/km. SIMIT developed ultra-low-noise superconducting single-photon detectors.

By implementing multiple filters at temperatures of 40 K and 2.2 K to suppress dark counts caused by thermal radiation, the noise of the single-photon detectors was reduced to around 0.02 cps. Furthermore, the team also developed a dual-band phase estimation scheme to avoid the spontaneous Raman scattering noise, reducing the system noise to below 0.01 Hz.

Based on the aforementioned technological developments, the team achieved TF-QKD over a record distance of 1,002 km, with a key rate of 0.0034 bps. This work not only verifies the feasibility of the SNS-TF-QKD scheme at extremely long distances but also demonstrates that this protocol can achieve high key rates in many practical scenarios.

The success of this study holds significant implications for the advancement of secure quantum communication. It opens up new possibilities for long-distance quantum key distribution and paves the way for the realization of high-speed intercity quantum communication networks.

Global Top 7 Companies Accounted for 73% of total Quantum Key Distribution (QKD) market (QYResearch, 2021)

Quantum Key Distribution (QKD) uses physics instead of mathematics to encode messages, which provides greater security.

The genesis of QKD (Quantum Key Distribution) traces back to the late 1960s, when Stephen Wiesner first proposed the idea of encoding information on photons to securely transfer messages. In 1984, the physicist Charles Bennett and cryptographer Gilles Brassard worked together to mature this idea by introducing the first QKD protocol, known as “BB84”. Five years later, they built the first QKD prototype system which was said to be “secure against any eavesdropper who happened to be deaf” as it made audible noises while encoding crypto key onto single photons.

From its relatively humble beginnings, QKD has gained global interest as a unique cybersecurity solution with active research groups across North America, Europe, Australia, and Asia.

According to the new market research report “Global Quantum Key Distribution (QKD) Market Report 2023-2029”, published by QYResearch, the global Quantum Key Distribution (QKD) market size is projected to reach USD 6.82 billion by 2029, at a CAGR of 35.7% during the forecast period.

you change your reality like you change your mind. except most of you don't even change your mind. you sit in it, like a cat curling up in the same sunspot, convinced that because it's warm now, it'll always be warm. but reality isn't a sunspot; it's a flickering bulb, and if you know anything about quantum mechanics or mid-century romance films, you'd know that a flickering bulb can be rewired, replaced, made to hum at a different frequency entirely.

Forgotten property of the electron

Physical discovery opens up new avenues for “orbitronics”

The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists at Forschungszentrum Jülich have now discovered that in certain materials it is not only preserved but can even be actively controlled. This is due to a property of the crystal structure called chirality, which also influences many other processes in nature. The discovery has the potential to lead to a new class of electronic components capable of transmitting information with exceptional robustness and energy efficiency.

From electronics to spintronics, and now to orbitronics: In classical electronics, it is primarily the charge of the electron that counts. In modern approaches such as quantum computing and spintronics, the focus has shifted to the electron’s spin. Now, another property is entering the spotlight: orbital angular momentum (OAM). In simple terms, OAM describes how the electron moves within an atom – not in a classical orbit, but as a quantum mechanical distribution within an orbital.

“For decades, spin was considered the key parameter for new quantum-based technologies. But orbital angular momentum also has great potential as an information carrier – and is significantly more robust,” explains Dr. Christian Tusche from the Peter Grünberg Institute (PGI-6) at Forschungszentrum Jülich. The physicist is one of the lead authors of the study published in the renowned journal Advanced Materials.

The orbital angular momentum is one of the fundamental quantum numbers of the electron, similar to spin, which describes the apparent rotation of the electron. However, OAM is rarely observable in crystals. It is usually suppressed by the symmetrical electric and magnetic fields in the crystal lattice – an effect known as “quenching.”

In so-called chiral materials such as the cobalt silicide (CoSi) studied, this is different, as the team led by Christian Tusche, together with partners in Taiwan, Japan, Italy, the US, and Germany, has now been able to show. The word “chiral” comes from the ancient Greek “cheir” for hand. “These crystal structures lack mirror symmetry and are either left- or right-handed – just like the human hand. You can turn them around and they remain mirror images of each other,” explains Dr. Tusche. Chirality occurs frequently in nature. Sugar molecules, amino acids, and DNA all exhibit chiral structures.

Using high-resolution momentum microscopy and circularly polarized light, the researchers were able to resolve the orbital angular momentum in the chiral semiconductor for the first time – both inside the crystal and on its surface. For the measurements, they used the NanoESCA momentum microscope operated by Forschungszentrum Jülich at the Elettra synchrotron in Trieste, Italy. They discovered that the handedness of the crystal – left- or right-handed – predictably affects the orbital angular momentum of the electrons.

New link between crystal structure and electron

“Our results show that the structure of the crystal directly influences the angular momentum of the electrons – an effect that we were able to measure directly. This opens up a whole new door for materials research and information processing,” emphasizes Jülich experimental physicist Dr. Ying-Jiun Chen.

Dr. Dongwook Go, theoretical physicist at the Peter Grünberg Institute (PGI-1) in Jülich, adds: “The discovery is particularly important for the emerging field of orbitronics, which uses orbital angular momentum as an information carrier for the next generation of quantum technology.”

A characteristic feature of the resulting orbital angular momentum texture are differently formed Fermi arcs: open, arc-shaped structures that become visible in so-called momentum space representations, as generated by momentum microscopy. This opens up new perspectives for applications: In the future, information could be transmitted and stored not just via the charge or spin of electrons, but also through the direction and orientation of their orbital angular momentum. This so-called orbitronics – electronics based on orbital properties – could thus provide the foundation for a new class of electronic devices.

Potential for different applications

The EU is funding the development of this future technology as part of the EIC Pathfinder project OBELIX, in which Prof. Yuriy Mokrousov from the University of Mainz is also involved. The theoretical physicist is also group leader at the Peter Grünberg Institute (PGI-1) in Jülich and contributed fundamental theoretical models to the recent discovery.

Prof. Claus Michael Schneider also sees great promise: “For instance, it seems conceivable to use orbital angular momentum as an information carrier. Or one might employ circularly polarized light to selectively influence a crystal’s chirality, enabling a light-controlled, non-mechanical switch as an alternative to the transistor. Furthermore, coupling between orbital angular momentum and spin could allow integration into existing spintronics concepts—for example, in hybrid quantum devices,” says the director of the Peter Grünberg Institute for Electronic Properties (PGI-6) at Forschungszentrum Jülich.

Engineers Achieve Multiplexing Entanglement In Quantum Network

— By California Institute of Technology | February 26th, 2025

Laying the groundwork for quantum communication systems of the future, engineers at Caltech have demonstrated the successful operation of a quantum network of two nodes, each containing multiple quantum bits, or qubits—the fundamental information-storing building blocks of quantum computers.

To achieve this, the researchers developed a new protocol for distributing quantum information in a parallel manner, effectively creating multiple channels for sending data, or multiplexing. The work was accomplished by embedding ytterbium atoms inside crystals and coupling them to optical cavities—nanoscale structures that capture and guide light. This platform has unique properties that make it ideal for using multiple qubits to transmit quantum information-carrying photons in parallel.

"This is the first-ever demonstration of entanglement multiplexing in a quantum network of individual spin qubits," says Andrei Faraon (BS '04), the William L. Valentine Professor of Applied Physics and Electrical Engineering at Caltech. "This method significantly boosts quantum communication rates between nodes, representing a major leap in the field."

The work is described in a paper published on February 26 in the journal Nature. The lead authors of the paper are Andrei Ruskuc (Ph.D. '24), now a postdoctoral fellow at Harvard University, and Chun-Ju Wu, a graduate student at Caltech, who completed the work in Faraon's lab.

Just as the internet connects with the classical computers we are accustomed to using today, the quantum networks of the future will connect quantum computers that exist in different physical locations.

When working with the quantum realm, researchers are dealing with the miniscule scale of individual atoms and of photons, the basic particles of light. At this scale, matter does not behave according to classical physics; instead, quantum mechanics are at play.

One of the most important and bizarre concepts in quantum mechanics is that of entanglement, where two or more objects such as atoms or photons are inextricably linked regardless of their physical separation. This connection is so fundamental, that one particle cannot be fully described without reference to the other. As a result, measuring the quantum state of one also provides information about the other, which is key to quantum communication.

In quantum communication, the goal is to use entangled atoms as qubits to share, or teleport, quantum information. The key challenge that has thus far limited communication rates is the time it takes to prepare qubits and to transmit photons.

"Entanglement multiplexing overcomes this bottleneck by using multiple qubits per processor, or node. By preparing qubits and transmitting photons simultaneously, the entanglement rate can be scaled proportionally to the number of qubits," says Ruskuc.

In the new system, the two nodes are nanofabricated structures made from crystals of yttrium orthovanadate (YVO4). Lasers are used to excite ytterbium atoms (Yb3+), a rare-earth metal, within these crystals, causing each atom to emit a photon that remains entangled with it. Photons from atoms in two separate nodes then travel to a central location where they are detected. That detection process triggers a quantum processing protocol that leads to the creation of entangled states between pairs of ytterbium atoms.

Each node has many ytterbium atoms within the YVO4 crystal, so there are plenty of available qubits. However, each of those atoms has a slightly different optical frequency caused by imperfections within the crystal.

"This is like a double-edged sword," Ruskuc says. On one hand, the differing frequencies allow the researchers to fine-tune their lasers to target specific atoms. On the other, scientists previously believed that the corresponding differences in photon frequencies would make it impossible to generate entangled qubit states.

"That's where our protocol comes in. It is an innovative way to generate entangled states of atoms even when their optical transitions are different," Ruskuc says.

In the new protocol, the atoms undergo a kind of tailored quantum processing in real time once the photons are detected at the central location. The researchers call this processing "quantum feed-forward control."

"Basically, our protocol takes this information that it received from the photon arrival time and applies a quantum circuit: a series of logic gates that are tailored to the two qubits. And after we've applied this circuit, we are left with an entangled state," Ruskuc explains.

The team's YVO4 platform can accommodate many qubits—in this work, each node contained approximately 20. "But it may be possible to increase that number by at least an order of magnitude," says co-author Wu.

"The unique properties of rare-earth ions combined with our demonstrated protocol pave the way for networks with hundreds of qubits per node," Faraon says. "We believe this work lays a robust foundation for high-performance quantum communication systems based on rare-earth ions."

Additional Caltech authors of the paper, "Multiplexed Entanglement of Multi-emitter Quantum Network Nodes," are graduate student Emanuel Green; AWS Quantum Postdoctoral Scholar Research Associate Sophie L. N. Hermans; graduate student William Pajak; and Joonhee Choi of Stanford University, a former postdoctoral scholar from Faraon's lab. Device nanofabrication was performed in the Kavli Nanoscience Institute at Caltech.

HSR Lore

Ratio does actually have a fanclub in canon.

The Mechanical City is a real place in HSR, and is a key location in the Mechanical Emperor’s Wars, which are key events in HSR’s timeline (SimUni players will know). Although I made up the specific Siege of the Mechanical City event, it’s very plausible that it happened, given that it’s a war and all. 

Months after writing this chapter one of my friends came up with a theory that the roots of Attini (as in Attini peacock) come from the word Attouine, which could mean that Attini would canonically be the right way to denote something as being of-Attouine. I’m just going to pass it off as New vs. Old Attouinean linguistic quirks. 

Other Notes 

An ideal black body in quantum mechanics absorbs all incident energy and reflects / transmits none. In other words, it has a unique absolutely stable distribution of radiative intensity that can persist in thermodynamic equilibrium. It’s a theoretical ideal, and for Ratio to have developed a method to generate energy from something like this is bordering on insane because IT DOESN’T EXIST. Obviously it’s all fiction but phewwww. But also, because it doesn’t transmit or reflect any energy, the level of energy it generates basically doesn’t change (or sees minimal changes), which means that in order to be an efficient energy generator, it needs to ALREADY be capable of emitting high energy, i.e. it needs to be really fucking hot. I made up the existence of QUA-locked materials, but basically think of them as objects similar to dark matter: extremely cold and completely non-interactive with light or other forms of electromagnetic radiation — basically, not prone to the effects of radiation. While dark matter doesn’t disrupt energy directly, its gravitational influence can affect fields and charged particles. By projecting QUA-locked materials in a certain direction, they will pull particles towards themselves and apart from each other, hence disrupting flows of energy like Aspects’, which is why Ratio and Aventurine had to make the distinction between omnidirectional and monodirectional models. And I really hope I explained the Azyldine bit well enough already because I don’t have it in me to come up with another explanation. (Why I should not be a teacher part 264836483.) Anyways. Fiction that makes a little bit of irl sense hooray!

Any table mats made from non-cloth materials can become painful to put weight on real quick. You don’t even realize it’s digging into your skin until 5min later, by which point your elbows (it’s usually elbows) will be marked red.

Nina Simone was an American songwriter, pianist, composer, arranger and civil rights activist. She was also a fantastic jazz singer. 

Ileoscopes don’t exist irl, although ileoscopies do (they’re examinations of the ileum, a body part in the digestive tract). Since there are so many alien species in HSR, just imagine that Ratio invented a universal ileoscope for a non-humanoid genus that can’t use endoscopes. 

Aesculapius was the Roman god of medicine. As such, Aesculapian means anything medicine-related. This is probs common knowledge but I’m putting it here anyway because I did have to search it up, if only to check the spelling.

With the right finish, oak wood and ash wood can actually be quite hard to tell apart!

Blockchain Technology, Quantum Computing’s Blockchain Impact

What Is Blockchain?

Definition and Fundamental Ideas

Blockchain technology is a decentralized digital ledger that records transactions across several computers without allowing changes. First given as Bitcoin’s basis. Banking, healthcare, and supply chain management employ bitcoin-related technologies.

Immutability, transparency, and decentralization characterize blockchain. Decentralization on peer-to-peer networks eliminates manipulation and single points of failure. Blockchain transparency is achieved by displaying the whole transaction history on the open ledger. It enhances transaction accountability and traceability. Finally, immutability means a blockchain transaction cannot be amended or erased. This is feasible via cryptographic hash algorithms, which preserve data and blockchain integrity.

These ideas make blockchain a desirable choice for protecting online transactions and automating procedures in a variety of sectors, which will boost productivity and save expenses. One of the factors driving the technology’s broad interest and uptake is its capacity to foster security and trust in digital interactions.

Key Features of Blockchain Technology

Blockchain, a decentralized digital ledger, may change several sectors. Decentralization, which removes a single point of control, is one of its most essential features. Decentralization reduces corruption and failure by spreading data over a network of computers.

The immutability of blockchain technology is another essential component. It is very hard to change data after it has been stored on a blockchain. This is due to the fact that every block establishes a safe connection between them by including a distinct cryptographic hash of the one before it. This feature makes the blockchain a reliable platform for transactions by guaranteeing the integrity of the data stored there.

Blockchain technology is more secure than traditional record-keeping. Data is encrypted to prevent fraud and unwanted access. Data-sensitive businesses like healthcare and finance need blockchain’s security.

How Blockchain and Quantum Computing Intersect

Enhancing Security Features

Blockchain and quantum computing appear to increase digital transaction security. Blockchain technology uses distributed ledger technology to record transactions decentralizedly. Quantum computing may break several blockchain encryption methods due to its powerful processing. But this danger also encourages the creation of blockchains that are resistant to quantum assaults by including algorithms that are safe from such attacks.

By allowing two parties to generate a shared random secret key that is only known to them, quantum key distribution (QKD) is a technique that employs the concepts of quantum physics to secure communications. This key may be used to both encrypt and decode messages. The key cannot be intercepted by an eavesdropper without creating observable irregularities. This technique may be used into blockchain technology to improve security and make it almost impenetrable.

Quantum computing may speed up complex cryptographic procedures like zero-knowledge proofs on blockchains, boosting security and privacy. These advances might revolutionize sensitive data management in government, healthcare, and finance. To explore how quantum computing improves blockchain security, see Quantum Resistant Ledger, which discusses quantum-resistant cryptographic techniques.

Quantum Computing’s Impact on Blockchain Technology

By using the ideas of quantum physics to process data at rates that are not possible for traditional computers, quantum computing provides a substantial breakthrough in computational power. Blockchain technology, which is based on traditional cryptographic concepts, faces both possibilities and dangers from this new technology.

The main worry is that many of the cryptographic techniques used by modern blockchains to provide security might be cracked by quantum computers. The difficulty of factoring big numbers, for example, is the foundation of most of today’s cryptography, a work that quantum computers will do exponentially quicker than conventional ones. If the cryptographic underpinnings of blockchain networks are hacked, this might possibly expose them to fraud and theft concerns.

But the use of quantum computing also presents blockchain technology with revolutionary possibilities. Blockchains with quantum enhancements may be able to execute transactions at very fast rates and with improved security features, far outperforming current networks. To protect blockchain technology from the dangers of quantum computing, researchers and developers are actively investigating quantum-resistant algorithms.

Quantum computing, once a theoretical concept, is now an impending reality. The development of quantum computers poses significant threats to the security of many cryptographic systems, including Bitcoin. Cryptographic algorithms currently used in Bitcoin and similar systems may become vulnerable to quantum computing attacks, leading to potential disruptions in the blockchain ecosystem. The question arises: What will be the fate of Bitcoin in a post-quantum cryptographic world?

Bitcoin relies on two cryptographic principles: the Elliptic Curve Digital Signature Algorithm (ECDSA) and the SHA-256 hashing function. The ECDSA is used for signing transactions, which verifies the rightful owner of the Bitcoin. On the other hand, the SHA-256 hashing function is used for proof-of-work mechanism, which prevents double-spending. Both principles are expected to become vulnerable in the face of powerful quantum computers.

Quantum Threat to Bitcoin

Quantum computers, due to their inherent nature of superposition and entanglement, can process information on a scale far beyond the capability of classical computers. Shor's Algorithm, a quantum algorithm for factoring integers, could potentially break the ECDSA by deriving the private key from the public key, something that is computationally infeasible with current computing technology. Grover's Algorithm, another quantum algorithm, can significantly speed up the process of finding a nonce, thus jeopardizing the proof-of-work mechanism.

Post-Quantum Cryptography

In a post-quantum world, Bitcoin and similar systems must adapt to maintain their security. This is where post-quantum cryptography (PQC) enters the scene. PQC refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against an attack by a quantum computer. These algorithms provide a promising direction for securing Bitcoin and other cryptocurrencies against the quantum threat.

Bitcoin in the Post Quantum World

Adopting a quantum-resistant algorithm is a potential solution to the quantum threat. Bitcoin could potentially transition to a quantum-resistant cryptographic algorithm via a hard fork, a radical change to the blockchain protocol that makes previously invalid blocks/transactions valid (or vice-versa). Such a transition would require a complete consensus in the Bitcoin community, a notoriously difficult achievement given the decentralized nature of the platform.

Moreover, the Bitcoin protocol can be updated with quantum-resistant signature schemes like the Lattice-based, Code-based, Multivariate polynomial, or Hash-based cryptography. These cryptosystems are believed to withstand quantum attacks even with the implementation of Shor's Algorithm.

Additionally, Bitcoin could integrate quantum key distribution (QKD), a secure communication method using a cryptographic protocol involving components of quantum mechanics. It enables two parties to produce a shared random secret key known only to them, which can be used to encrypt and decrypt messages.

Conclusion

In conclusion, the advent of quantum computers does indeed pose a threat to Bitcoin's security. However, with the development of post-quantum cryptography, there are potential solutions to this problem. The future of Bitcoin in a post-quantum world is likely to depend on how quickly and effectively these new cryptographic methods can be implemented. The key is to be prepared and proactive to ensure the longevity of Bitcoin and other cryptocurrencies in the face of this new quantum era.

While the quantum threat may seem daunting, it also presents an opportunity - an opportunity to improve, to innovate, and to adapt. After all, the essence of survival lies in the ability to adapt to change. In the end, Bitcoin, like life, will find a way.

⠀ ⠀welcome to the manifesting seance club.

sit down. no, seriously, sit. the spirits are pacing. the stars are staring. you’re being perceived in real time.

AHEM. before we begin, a moment of academic showboating: the knowledge i am about to graciously, magnanimously, almost divinely bestow upon you has been extracted from sources so reputable, so critically esteemed, that to ignore them would be akin to walking past the oracle at delphi and asking a guy named kevin for directions instead. sources such as . . . ୨୧

" esoteric astrology " by alice a. bailey " the astrology of fate " by liz greene " saturn : a new look at an old devil " by liz greene " hellenistic astrology : the study of fate and fortune " by chris brennan

all of which are required reading if you want to, you know, actually know things. otherwise, feel free to just wing it. people have built entire careers off of significantly less.

anyway, welcome to manifesting séance club. which is to say, a completely necessary and not at all ridiculous initiative in which i, with the help of the cosmos, will deign to tell you exactly how you should be manifesting based on your zodiac sign. you can take this with the weight of divine scripture, or you can take it with a large, gratuitous grain of salt and see this as entertainment only. either way, the planets have spoken.

 　　. . . now, let’s see what they say about you

⠀⠀ ✶ ⠀⠀ 𝐚ries⠀⠀⠀⠀⠀

omen : aries manifests like they’re storming the beaches of normandy. it’s not a process, it’s an ambush. every morning, a new battle plan scrawled on a napkin, ripped in half by noon. immediate results or nothing at all. there’s no patience for the slow drip of reality conforming to their will. they want tectonic shifts, they want fireworks, they want god himself to clock in some overtime.

fate’s verdict : cosmic tantrum. they don’t wait for the stars to align, they drag them into formation. but the universe prefers the long game, and aries does not. the lesson here is simple . . . it will happen, but not in the way you’re trying to force it. stop manifesting like you’re throwing grenades into the void.

⠀꒰ prescription : let go. just a little. just enough to let the universe breathe. ⠀manifestation is not a hostage situation.

⠀⠀ ✶ ⠀⠀ 𝐭aurus⠀⠀⠀⠀⠀

omen : taurus manifests like an investment banker, a landowner, a careful deity counting their coins before distributing miracles. they do not believe in asking the universe for favours without putting down collateral, vision boards, rituals, journals so thick they could stop a bullet. the future is built in increments, brick by brick. manifestation as empire-building.

fate’s verdict : a little too grounded, a little too rational. taurus sometimes mistakes manifestation for a to-do list rather than an act of faith. this is the hill they will die on, ledger in hand.

⠀꒰ prescription : loosen the grip. manifestation isn’t a contract, you don’t need a ⠀cosigner. ask. then trust that it’s being worked out somewhere beyond your ⠀jurisdiction.

⠀⠀ ✶ ⠀⠀ 𝐠emini⠀⠀⠀⠀⠀

omen : gemini manifests like a conspiracy theorist with a corkboard full of red string. everything is possible, every reality is within reach. they could be a doctor, a poet, a movie star, a revolutionary, sometimes all in the same afternoon. the problem is the sheer velocity of belief. one day they’re visualising love, the next they’ve decided celibacy is the key to enlightenment. their manifestations lack consistency, collapsing under their own contradictions.

fate’s verdict : too many tabs open. gemini’s mind is a quantum superposition of possibilities, but the universe prefers clarity. pick a lane. stay in it.

⠀꒰ prescription : write it down. once. no revisions. stick to it for longer than a week.

⠀⠀ ✶ ⠀⠀ 𝐜ancer⠀⠀⠀⠀⠀

omen : cancer manifests like a poet in a garret, talking into the dark, hoping the cosmos is listening. emotions are the currency, nostalgia the driving force. manifestation as longing. as a half-forgotten song. they dream in sepia tones, in candlelight and old film reels. they don’t just want something, they want to be consumed by it.

fate’s verdict : beautiful. but manifestation is an act of creation, not just yearning alone.

⠀꒰ prescription : clarify the vision. make it real, tangible, specific. want, but also ⠀act.

⠀⠀ ✶ ⠀⠀ 𝐥eo⠀⠀⠀⠀⠀

omen : leo manifests like a celebrity giving an acceptance speech before the award has even been announced. they assume the universe is their audience, their stage, their greatest admirer. naturally, their manifestations are grand, cinematic, dripping with self-belief. they don’t request, they declare. they don’t doubt, they expect.

fate’s verdict : they’re not wrong, but sometimes they rely too much on the applause. the universe doesn’t care about the optics, it cares about the energy behind them. manifestation is not performance art.

⠀꒰ prescription : make sure you want it for you. not for the audience, not for the ⠀applause, not for the standing ovation. just for you.

⠀⠀ ✶ ⠀⠀ 𝐯irgo⠀⠀⠀⠀⠀

omen : virgo manifests like an engineer drafting blueprints for god. meticulous, precise, airtight. a plan within a plan within a plan. they don’t just manifest . . . they optimise. they find flaws in their own dreams before they’ve even begun, tweaking and adjusting, searching for perfection before the universe even has a chance to deliver.

fate’s verdict : manifestation requires some degree of surrender. virgo’s approach is admirable, but they risk micromanaging the cosmos. control is an illusion. perfection is a myth.

⠀꒰ prescription : stop editing the vision. let it breathe. let it live.

⠀⠀ ✶ ⠀⠀ 𝐥ibra⠀⠀⠀⠀⠀

omen : libra manifests like an artist with too many unfinished canvases. they want everything, in all its beauty, but they can never quite decide what to ask for. they spend more time weighing options than actually committing to a vision. manifestation as a game of what-if.

fate’s verdict : indecision is the enemy. the universe responds to clarity, not hesitation. a wish half-made is a wish unheard.

⠀꒰ prescription : pick something. anything. stick to it. see it through.

⠀⠀ ✶ ⠀⠀ 𝐬corpio⠀⠀⠀⠀⠀

omen : scorpio manifests like a sorcerer muttering in a locked room, like an old god stirring in its sleep. manifestation as alchemy. as transformation. their will is absolute, their focus terrifying. they do not just ask for what they want, they become it.

fate’s verdict : powerful, but isolating. scorpio sometimes forgets that manifestation doesn’t have to be a solitary act, that the universe is not an adversary but an accomplice.

⠀꒰ prescription : soften. let it in. manifestation is not a lone pursuit.

⠀⠀ ✶ ⠀⠀ 𝐬agittarius⠀⠀⠀⠀⠀

omen : sagittarius manifests like an explorer mapping out an undiscovered country. they see possibility everywhere, in every corner of the universe. their manifestations are broad, open-ended, half-prayers, half-dares. they don’t demand, they leap.

fate’s verdict : good energy, unfocused. sagittarius needs to narrow the scope, sharpen the vision.

⠀꒰ prescription : be specific. manifestation is not a vague wish upon a star.

⠀⠀ ✶ ⠀⠀ 𝐜apricorn⠀⠀⠀⠀⠀

omen : capricorn manifests like an architect designing a cathedral that will take centuries to complete. slow, steady, methodical. they don’t just wish; they work. they lay foundations while others are still drafting dreams.

fate’s verdict : excellent, but exhausting. capricorn sometimes forgets that manifestation is not solely an act of labour. effort is crucial, but so is belief.

⠀꒰ prescription : trust. allow for miracles. not everything requires blood, sweat, and ⠀spreadsheets.

⠀⠀ ✶ ⠀⠀ 𝐚quarius⠀⠀⠀⠀⠀

omen : aquarius manifests like a mad scientist in a laboratory of their own making. their visions are radical, their ideas borderless. they do not want what others want. their manifestations often seem impossible until, suddenly, they’re not.

fate’s verdict : brilliant, but scattered. aquarius has a habit of overcomplicating what should be simple. manifestation is not always a revolution.

⠀꒰ prescription : simplify. sometimes the best way forward is the obvious one.

⠀⠀ ✶ ⠀⠀ 𝐩isces⠀⠀⠀⠀⠀

omen : pisces manifests like a dreamer lost in their own reverie. manifestation as fantasy, as daydream, as an ethereal whisper into the cosmos. they believe in miracles, in divine intervention, in the soft hand of fate guiding them.

fate’s verdict : beautiful, but passive. manifestation is co-creation, not just waiting for the stars to do the work.

⠀꒰ prescription : dream, but also know. the universe moves when you know.

Nature-inspired solar lasers could sustainably power space missions

International scientists, including a team from Heriot-Watt University, has announced plans to develop a revolutionary new way of harvesting solar energy in space.

The new technology would directly convert sunlight into laser beams, facilitating the transmission of power over vast distances, such as between satellites, from satellites to lunar bases, or even back to Earth. The approach is inspired by the way bacteria and other plants and organisms convert light energy into chemical energy—a process known as photosynthesis. Repurposing natural photosynthetic structures from nature will form a key component in the new laser technology.

If successful, their innovative technology could help global space agencies to power future endeavors such as lunar bases or missions to Mars, as well as open new pathways for terrestrial wireless power transmission and sustainable energy solutions globally.

The APACE project brings together researchers from the U.K., Italy, Germany and Poland to create the new type of solar-powered lasers, which will provide reliable, efficient power for the growing number of satellites and future space missions.

The system will repurpose light harvesting antennas of certain photosynthetic bacteria, which are highly efficient at absorbing ambient solar light and channeling its energy to a desired target location as part of their photosynthetic cycle.

The team plans to realize their idea under laboratory conditions first, before testing and refining its suitability for deployment into the space environment.

The researchers will begin by extracting and studying the natural light-harvesting machinery from specific types of bacteria that have evolved to survive in extremely low light conditions. These bacteria have specialized molecular antenna structures that can capture and channel almost every photon of light they receive—making them nature's most efficient solar collectors.

In parallel, the team will develop artificial versions of these structures and new laser materials that can work with both natural and artificial light-harvesters. These components will then be combined into a new type of laser material and tested in increasingly larger systems.

Unlike conventional semiconductor solar panels, which convert sunlight into electricity, their bio-inspired system builds on a sustainable organic platform with the potential for replication in space. It would then allow for the direct distribution of power without relying on an electric intermediary.

Professor Erik Gauger from the Institute of Photonics and Quantum Sciences at Heriot-Watt University is leading the theoretical modeling aspects of the project.

He explains, "Sustainable generation of power in space, without relying on perishable components sent from Earth represents a big challenge. Yet, living organisms are experts at being self-sufficient and harnessing self-assembly. Our project not only takes biological inspiration but goes one step beyond by piggybacking on functionality that already exists in the photosynthetic machinery of bacteria to achieve a breakthrough in space power.

"Our APACE project aims to create a new type of laser powered by sunlight. Regular sunlight is usually too weak to power a laser directly, but these special bacteria are incredibly efficient at collecting and channeling sunlight through their intricately designed light harvesting structures, which can effectively amplify the energy flux from sunlight to the reaction center by several orders of magnitude. Our project will make use of this level of amplification to convert sunlight into a laser beam without relying on electrical components.

"We already know it is possible to grow bacteria in space, for example through studies on the International Space Station. Some tough bacteria have even survived exposure to open space! If our new technology can be built and used on space stations, it could help to generate power locally and even offer a route to sending power to satellites or back to Earth using infrared laser beams.

"This technology has the potential to revolutionize how we power space operations, making exploration more sustainable while also advancing clean energy technology here on Earth. All major space agencies have lunar or Mars missions in their plans and we hope to help power them."

The research team expects to have its first prototype ready for testing within three years.

USPTO 13/573,002 claim: closer- cheaper given less attenuation over distance, less infrastructure needed

DARPA POWER ("Persistent Optical Wireless Energy Relay"): "develop a means of distributing energy wirelessly around the globe through airborne power transfer. First dreamed up by Nikola Tesla almost 100 years ago, if successful, this would be the most significant change to energy transfer since the first rollout of electrification almost 150 years ago. The program goals include demonstrating the key components of a resilient, speed-of-light energy network".

DARPA plans to create wireless energy transfer infrastructure to supply near-uninterruptable power to U.S. military bases worldwide. The plan, as reported by Popular Mechanics, is to use laser technology to beam electricity around the planet. Famously a dream of Nikola Tesla over 100 years ago, if successful, this technology, called fittingly enough POWER ("Persistent Optical Wireless Energy Relay"), would make the U.S. military less reliant on liquid fuel like diesel and vulnerable power lines, which can be intercepted or sabotaged by enemy forces. https://interestingengineering.com/innovation/darpa-laser-power-transfer

Power of Quantum Computing 02

Utilizing the Potential of Quantum Computing.

A revolutionary technology, quantum computing holds the promise of unmatched computational power. Development of quantum software is in greater demand as the field develops. The link between the complicated underlying hardware and the useful applications of quantum computing is provided by quantum software. The complexities of creating quantum software, its potential uses, and the difficulties developers face will all be covered in this article.

BY KARTAVYA AGARWAL

First, a primer on quantum computing.

Contrary to traditional computing, quantum computing is based on different principles. Working with qubits, which can exist in a superposition of states, is a requirement. These qubits are controlled by quantum gates, including the CNOT gate and the Hadamard gate. For the creation of quantum software, comprehension of these fundamentals is essential. Qubits and quantum gates can be used to create quantum algorithms, which are capable of solving complex problems more quickly than conventional algorithms. Second, there are quantum algorithms. The special characteristics of quantum systems are specifically tapped into by quantum algorithms. For instance, Shor's algorithm solves the factorization issue and might be a threat to traditional cryptography. The search process is accelerated by Grover's algorithm, however. A thorough understanding of these algorithms and how to modify them for various use cases is required of quantum software developers. They investigate and develop new quantum algorithms to address issues in a variety of fields, including optimization, machine learning, and chemistry simulations. Quantum simulation and optimization are the third point. Complex physical systems that are difficult to simulate on traditional computers can be done so using quantum software. Scientists can better comprehend molecular structures, chemical processes, and material properties by simulating quantum systems. Potential solutions for logistics planning, financial portfolio management, and supply chain optimization are provided by quantum optimization algorithms. To accurately model these complex systems, quantum software developers work on developing simulation frameworks and algorithm optimization techniques. The 4th Point is Tools and Languages for Quantum Programming. Programming languages and tools that are specific to quantum software development are required. A comprehensive set of tools and libraries for quantum computing are available through the open-source framework Qiskit, created by IBM. Another well-known framework that simplifies the design and simulation of quantum circuits is Cirq, created by Google. Incorporating quantum computing with traditional languages like C, the Microsoft Quantum Development Kit offers a quantum programming language and simulator. These programming languages and tools are utilized by developers to create quantum hardware, run simulations, and write quantum circuits. The 5th point is quantum error correction. Störungs in the environment and flaws in the hardware can lead to errors in quantum systems. Quantum computations are now more reliable thanks to quantum error correction techniques that reduce these errors. To guard against errors and improve the fault tolerance of quantum algorithms, developers of quantum software employ error correction codes like the stabilizer or surface codes. They must comprehend the fundamentals of error correction and incorporate these methods into their software designs. Quantum cryptography and secure communication are the sixth point. Secure communication and cryptography are impacted by quantum computing. Using the concepts of quantum mechanics, quantum key distribution (QKD) offers secure key exchange and makes any interception detectable. Post-quantum cryptography responds to the danger that quantum computers pose to already-in-use cryptographic algorithms. To create secure communication protocols and investigate quantum-resistant cryptographic schemes, cryptographers and quantum software developers work together. Point 7: Quantum machine learning A new field called "quantum machine learning" combines machine learning with quantum computing. The speedup of tasks like clustering, classification, and regression is being studied by quantum software developers. They investigate how quantum machine learning might be advantageous in fields like drug discovery, financial modeling, and optimization. Point 8: Validation and testing of quantum software. For accurate results and trustworthy computations, one needs trustworthy quantum software. Different testing methodologies are used by quantum software developers to verify the functionality and efficiency of their products. To locate bugs, address them, and improve their algorithms, they carry out extensive testing on simulators and quantum hardware. Quantum software is subjected to stringent testing and validation to guarantee that it produces accurate results on various platforms. Point 9: Quantum computing in the study of materials. By simulating and enhancing material properties, quantum software is crucial to the study of materials. To model chemical processes, examine electronic architectures, and forecast material behavior, researchers use quantum algorithms. Variational quantum eigensolvers are one example of a quantum-inspired algorithm that makes efficient use of the vast parameter space to find new materials with desired properties. To create software tools that improve the processes of materials research and discovery, quantum software developers work with materials scientists. Quantum computing in financial modeling is the tenth point. Quantum software is used by the financial sector for a variety of applications, which helps the industry reap the benefits of quantum computing. For portfolio optimization, risk assessment, option pricing, and market forecasting, quantum algorithms are being investigated. Financial institutions can enhance decision-making processes and acquire a competitive advantage by utilizing the computational power of quantum systems. Building quantum models, backtesting algorithms, and converting existing financial models to quantum frameworks are all tasks carried out by quantum software developers.
