Free Courses on IBM Quantum Learning

IBM has launched a series of free course for learning the basics of quantum computing and how to use the IBM Quantum services (here the link).

At the moment I’m writing there are four courses:

Basics of quantum information

First unit in the series, the course explains the basis of quantum computing at a detailed mathematical level, it requires knowing a bit of linear algebra, but also fascinating subjects like: quantum teleportation (no, sadly it’s not like Star Trek) and superdense coding.

Fundamentals of quantum algorithms

This second unit explores the advantages of quantum computers over classical computers

Variational algorithm design

This course teaches how to write variational algorithms and how to use Qiskit, the IBM API for quantum computing.

Practical introduction to quantum-safe cryptography Quantum computers can do what a classical computer can’t: use brute force and be quick, so they can break common cryptography. This course teaches how to use encryption that cannot be break so easily.

This link, often referred to as a quantum key distribution, is based on the principle of quantum entanglement, where the states of two particles become intertwined in such a way that any change in one particle instantaneously affects the other, regardless of the distance separating them.

This phenomenon guarantees the security of the communication channel, as any attempt to intercept or eavesdrop on the transmitted quantum information would disrupt the delicate entanglement, leaving clear traces of tampering. This fundamental principle, known as the Heisenberg Uncertainty Principle, dictates that any observation of a quantum system alters its state, making surreptitious decryption impossible without alerting the parties involved.

The mind-bending implications of quantum encryption extend beyond secure communication channels. It has the potential to fundamentally transform industries reliant on data privacy, including finance, healthcare, government, and defense. Financial transactions, medical records, and classified government communications—all stand to benefit from the ironclad protection offered by quantum encryption.

However, the practical implementation of quantum encryption is not without challenges. Quantum systems are exquisitely delicate and susceptible to disturbances from their environment, which can lead to errors in transmission. Researchers have been diligently working to develop error correction techniques and robust quantum hardware to overcome these hurdles and make quantum encryption a viable reality.

Totally Random: Why Nobody Understands Quantum Mechanics (A Serious Comic on Entanglement) – Book Review

The title of this book, as you can see above, is long as a chapter itself, so I’ll refer to it in this review more shortly as “Totally Random”. “Totally Random” has the ambitious intent of making Quantum Entanglement clear for everyone.

But what is Quantum Entanglement? If I can explain it without errors, you’ll have the proof the book works, so I’ll try my best.

Some quantum particles (photons or electron for example) can be induced in a state called “entanglement” in which their behavior is striclty correlated, they become like a single particle.

If you call your particles Alice and Bob, whatever thing Alice does, Bob seems to know instantly, even if they are separeted in space and cannot comunicate by any known mean, so if Alice and Bob were real people and not particles, if Alice is having tea for breakfast on Earth, then Bob is having tea for breakfast wherever he is, even on Jupiter. If Alice wakes up and wants an espresso with cocoa, well Bob wants the same (no matter if Bob prefers tea), and viceversa. The point is: if you observe Alice doing something, whenever you observe Bob you get the same result. Bob and Alice can also decide to do always the opposite thing of the other one, but the point is: they follow a pattern, they seem to communicate faster than light, but you all know that nothing in this universe can travel faster than light which is strictly equivalent to say “Nobody puts Einstein in a corner”.

Fundamentally quantum entanglement is simply the most puzzling thing in all quantum mechanics, the more exciting, the more promising and sometimes it seems really like magic. Many phyiscs have been fashinated by this phenomenon and the most important ones and their theories are illustrated in the book. The authors of “Totally Random” are father and child, namely Jeffrey Bub (a professor at the University of Maryland who studied physics with Bohm and philosophy with Popper) and Tanya Bub who got a degree in philosopy and studied art and had the courage to coauthor a book with her father (I suppose it isn’t easy to get the last word in such a scenario). The comic has a simple style, functional to the argument, so no fancy scenes Marvel-style with maybe a superhero Schrödinger and his loyal cat in a cape fighting with some kind of enemy, but the most important scientists of the field appear in the book, illustrating their different point of views about entanglement ( and yes, Schrödinger and his cat appear in the book, but not with a cape). The books tries to explain also important possible applications of entanglement like quantum teleportation or quantum cryptography. The most of the book is dedicated to explain Bell’s inequality: a mathematical theorem that shows that entanglement cannot be caused by any kind of rigging of the experiments and I think the authors do really a good job about it, explaining the correlation between quantum particles as the toss of Quoins, special coins correalted through a machine called Super Quantum Entangler PR01. The book is a very likeble read, but despite being funny, it has a very serious long list of references at the end, including the source of all the phrases attributed to scientists. I really enjoyed this reading: I saw a video about quantum entanglement and I got mesmerized by the idea of mysterious communication faster than light, and searched for list of books about it, one of which listed many university books and this comic. As any serious person raised with bread and comics would do, I choose the comic book as first read about the argument and I think I did well.

The book has page dedicated with extra material:

Quantum cryptography uses quantum mechanics principles to encrypt the plaintext

Quantum cryptography, according to the definition, uses quantum mechanics and quantum algorithms to make it technically unhackable. Consider a data transfer between two parties, sender and receiver. The key used to cypher the plaintext in quantum cryptography is known as quantum key distribution (QKD), which is a sequence of photons used to transmit data over an optical fibre cable. The parties involved will be able to determine what the key is and whether it has been compromised by a third party by comparing measurements of the properties of these photons.

Bitcoin in a Post Quantum Cryptographic World

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.
