Solid-State Quantum Emitters The Future Of Quantum Tech

Solid-State Quantum Emitters

Pioneering research into solid-state quantum emitters, nanoscale light sources that enable safe data transfer, precise measurements, and powerful computation, is accelerating quantum communication and sensing technologies. (Alan) Quantum News Hound reports that an exhaustive analysis by scientists at the University of Electronic Science and Technology of China emphasises their importance in scalable quantum computing across three primary material platforms:

The Basics of Quantum Emitters

Understand Quantum Emitter Basics Quantum emitters can produce entangled photon pairs and single photons upon request. Atomic systems require precise trapping, but solid-state emitters are embedded in materials, making nanofabrication for scaled quantum technologies easier.

Key Performance Indicators

Several key measures evaluate performance:

Radiative Rate & Spectra/Linewidth: High radiative rates (hundreds of MHz or GHz) are preferred for photon creation. The coherent zero-phonon line (ZPL) should be close to unity and have a short, transform-limited linewidth.

Single-Photon Purity: g^(2)(0), preferably 0, indicates genuine single-photon emission, excluding simultaneous photons.

Quantifying photon identicality is fundamental to quantum interference. Evaluation uses Hong-Ou-Mandel (HOM) interference, where ideal indistinguishable photons have unit contrast. High indistinguishability requires minimizing dephasing. Photon efficiency controls brightness. Integrated optical cavity emitters increase emission rate and collecting efficiency (Purcell effect).

The ability to deterministically release one photon every trigger pulse is called “on-demand operation.” To provide coherent control, resonant π-pulses are used to excite the emitter with near-unit fidelity. This requires separating the pump laser and released photons.

Quantum networks require a matter qubit with extended coherence durations and a photonic interface. Scalability requires telecom wavelength emission, multi-emitter consistency, and nanophotonic circuit compatibility.

Potential Material Platforms

Research focusses on three solid-state platforms:

The speed and brightness of quantum dots (QDs) make them a highly advanced photonic quantum resource. QDs have 98% entangled photon fidelity and >99% single-photon purity. Emissions influence telecom O- and C-band. Even though spin coherence (microsecond to sub-millisecond) is shorter than diamond/SiC defects, noise reduction improves their properties.

Diamond Defect Centres: Even at room temperature, diamond defect centres have extended spin coherence periods, making them ideal for information processing and quantum sensing. Group IV defects (SiV-, GeV-, and SnV-) contribute more ZPL, but NV-centers have stable spins. High single-photon purity (97–99%) is normal, but indistinguishability is difficult. Photonic structure integration is progressing despite fabrication issues.

Silicon carbide (SiC): Defect centres' interesting quantum properties and compatibility with semiconductor architecture are making them more popular. SiC has a wide bandgap and good heat conductivity. With emission from 600 nm to the telecom O-band, it has many problems. SiC has excellent spin properties and prospective spin-photon interfaces at ambient temperature due to divacancy centres' five-second coherence durations. SiCOI supports advanced integrated nanophotonic devices.

Challenges Overcame, Future Prospects

Important concerns persist across platforms:

Extension of Coherence: Cavity augmentation improves QD performance at higher temperatures.

Scalable Fabrication: Material variability and emitter location are crucial for large-scale integration.

Despite improvements in room-temperature emitters, cryogenic conditions are usually best for performance.

Telecom wavelengths: Long-distance communication requires frequency conversion or direct emission.

Rare-earth ions and 2D materials are promising, therefore the field is growing swiftly. Research, engineering, and industry must collaborate to fully realize quantum emitters' potential for reliable quantum technologies. Commercializing III-V QD is a big step towards widespread adoption.

Researchers at Heriot-Watt University have made a discovery that could pave the way for a transformative era in photonic technology. For decades, scientists have theorized the possibility of manipulating the optical properties of light by adding a new dimension—time. This once-elusive concept has now become a reality thanks to nanophotonics experts from the School of Engineering and Physical Sciences in Edinburgh, Scotland. Published in Nature Photonics , the team's breakthrough emerged from experiments with nanomaterials known as transparent conducting oxides (TCOs)—a special glass capable of changing how light moves through the material at incredible speeds. These compounds are widely found in solar panels and touchscreens and can be shaped as ultra-thin films measuring just 250 nanometers (0.00025 mm), smaller than the wavelength of visible light. Led by Dr. Marcello Ferrera, Associate Professor of Nanophotonics, of the Heriot-Watt research team, supported by colleagues from Purdue University in the US, managed to "sculpt" the way TCOs react by radiating the material with ultra-fast pulses of light. Remarkably, the resulting temporally engineered layer was able to simultaneously control the direction and energy of individual particles of light, known as photons, a functionality which, up until now, had been unachievable.

Researchers trap atoms, force them to serve as photonic transistors

Researchers at Purdue University have trapped alkali atoms (cesium) on an integrated photonic circuit, which behaves like a transistor for photons (the smallest energy unit of light) similar to electronic transistors. These trapped atoms demonstrate the potential to build a quantum network based on cold-atom integrated nanophotonic circuits. The team, led by Chen-Lung Hung, associate professor of physics and astronomy at the Purdue University College of Science, has published their discovery in Physical Review X. "We developed a technique to use lasers to cool and tightly trap atoms on an integrated nanophotonic circuit, where light propagates in a small photonic 'wire,' or more precisely, a waveguide that is more than 200 times thinner than a human hair," explains Hung, who is also a member of the Purdue Quantum Science and Engineering Institute.

opened up the tweet machine again and they’re still going after the phd about how scent is used in lit lady. I think this is the longest version of legs I’ve seen a topic get on there.

i used to be one of those people who was a bit miffed by how disciplines with different workloads gave you the same title. i got over it, mostly because I’m some combination of a personal liberty minded person and an abysmal narcissist. in other words, it’s hard to get all that emotionally invested in this. I have my own business i need to attend to.

what I do think is interesting, though, is that there are some nat science phds who think this person is in a status competition with them. no, dr biotech & dr nanophotonics, she’s not going to be applying for the same jobs you are. additionally – nat science graduate students are paid for their research. humanities graduate students often aren’t. this isn’t much different from a chem BS and a philosophy BA having a bar fight. “I can’t believe we both have bachelors degrees!” like would it kill you to just focus on your own career. intellectual waste of time imo.

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.

New theory reveals the shape of a single photon 

A new theory, that explains how light and matter interact at the quantum level has enabled researchers to define for the first time the precise shape of a single photon. 

Research at the University of Birmingham, published in Physical Review Letters, explores the nature of photons (individual particles of light) in unprecedented detail to show how they are emitted by atoms or molecules and shaped by their environment. 

The nature of this interaction leads to infinite possibilities for light to exist and propagate, or travel, through its surrounding environment. This limitless possibility, however, makes the interactions exceptionally hard to model, and is a challenge that quantum physicists have been working to address for several decades. 

By grouping these possibilities into distinct sets, the Birmingham team were able to produce a model that describes not only the interactions between the photon and the emitter, but also how the energy from that interaction travels into the distant ‘far field’. 

At the same time, they were able to use their calculations to produce a visualisation of the photon itself. 

First author Dr Benjamin Yuen, in the University’s School of Physics, explained: “Our calculations enabled us to convert a seemingly insolvable problem into something that can be computed. And, almost as a bi-product of the model, we were able to produce this image of a photon, something that hasn’t been seen before in physics.” 

The work is important because it opens up new avenues of research for quantum physicists and material science. By being able to precisely define how a photon interacts with matter and with other elements of its environment, scientists can design new nanophotonic technologies that could change the way we communicate securely, detect pathogens, or control chemical reactions at a molecular level for example. 

Co-author, Professor Angela Demetriadou, also at the University of Birmingham, said: “The geometry and optical properties of the environment has profound consequences for how photons are emitted, including defining the photons shape, colour, and even how likely it is to exist.” 

Dr Benjamin Yuen, added: “This work helps us to increase our understanding of the energy exchange between light and matter, and secondly to better understand how light radiates into its nearby and distant surroundings. Lots of this information had previously been thought of as just ‘noise’ - but there’s so much information within it that we can now make sense of, and make use of. By understanding this, we set the foundations to be able to engineer light-matter interactions for future applications, such as better sensors, improved photovoltaic energy cells, or quantum computing.”
