Quantum everything, scientific dogma, laws of the universe

Rediscovered a talk by Ross Anderson dismissing quantum mechanics and hence quantum computing. His very first words are: I was invited here to provide a dissenting view. He is basically saying that quantum mechanics are not different from classical physics. That’s what Bohm/De Broglie pilot wave theory argues but it has been dismissed many times […]

Quantum Computing, Its Principles, Capabilities and Challenges

So, I would like to see if there’s some other way out, and I want to emphasize, or bring the question here, because the discovery of computers and the thinking about computers has turned out to be extremely useful in many branches of human reasoning. For instance, we never really understood how lousy our understanding […]

Cryptography for the Post-Quantum World

When will quantum computers become relevant to cryptographers? Highlights from the talk Cryptography for the Post-Quantum World by Brian LaMacchia at Microsoft Research I am typically doing RSA with 2-kilobit keys, 2048-bit public keys. This is the product of 2 primes of each of about 1024 bits. What our paper showed is that if you […]

Quantum Computing for Computer Scientists

Lecture notes from the talk Quantum Computing for Computer Scientists by Andrew Helwer at Microsoft This talk discards hand-wavy pop-science metaphors and answers a simple question: from a computer science perspective, how can a quantum computer outperform a classical computer? Attendees will learn the following: Representing computation with basic linear algebra (matrices and vectors) The […]

State of the Art in Quantum Computing

Following are the lectures on quantum computing in increasing complexity order. The lectures give good overview of the science and technology as it works now. In the popular press, quantum computers are often presented not just as an exciting frontier of science and technology (which they are), but as magic devices that would work by […]

Limits of the Efficiently Computable

Two interesting and related talks, one on the physical limitations of computational power and the other on cryptography and computational puzzles presented to us by Nature herself. Quantum Computing and the Limits of the Efficiently Computable Breaking Codes and Finding Patterns Quantum Computing and the Limits of the Efficiently Computable Talk by Scott Aaronson, 2011 […]

IBM’s five-qubit universal quantum computer

Following are videos introducing IBM’s quantum computer and an article from Ars Technica that explains how it works. A Tour of the IBM Quantum Lab Jerry Chow, an experimental quantum computing scientist at IBM, introduces viewers to the Quantum Lab at the IBM T.J. Watson Research Center in New York. It is home to a […]
