What does that mean? Read the book! Also in , Urmila Mahadev gave a protocol, based on cryptography, by which a polynomial-time quantum computer i. To say it more simply, entangled provers can convince a polynomial-time verifier that an arbitrary Turing machine halts. Besides its intrinsic interest, a byproduct of this breakthrough was to answer a decades-old question in pure math, the so-called Connes Embedding Conjecture by refuting the conjecture. In a different direction, the last seven years have witnessed an astonishing convergence between quantum information and quantum gravity—something that was just starting when Quantum Computing Since Democritus appeared in , and that I mentioned as an exciting new direction.

The new proposal is that the CFT quantity might be not just complicated, but literally circuit complexity itself. Fanciful as that sounds, the truth is that no one has come up with any other proposal that passes the same sanity checks. A related new insight is that the nonlocal mapping between the AdS and CFT theories is not merely analogous to, but literally an example of, a quantum error-correcting code: the same mathematical objects that will be needed to build scalable quantum computers.

When Quantum Computing Since Democritus was first published, some people thought it went too far in elevating computer science, and computational complexity in particular, to fundamental roles in understanding the physical world. It seems far better for the book to stand as a record of what I knew and believed and cared about at a certain moment in time. But it does need to start somewhere. I hope you enjoy it.

OK, this will be my last blog post hawking Quantum Computing Since Democritus , at least for a while. But I do have four pieces of exciting news about the book that I want to share. Not factorial.

DOI: Aaronson Published 14 March Computer Science Written by noted quantum computing theorist Scott Aaronson, this book takes readers on a tour through some of the deepest ideas of maths, computer science and physics.

Full of insights, arguments and philosophical perspectives, the book covers an amazing array of topics. Beginning in antiquity with Democritus, it progresses through logic and set theory, computability and complexity theory, quantum computing, cryptography, the information content of quantum states and the interpretation of… Expand.
