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 […]

Neuroaesthetics: Beauty and the Brain

Couple quite interesting talks on evolution. Evolution of Beauty – Genetics How Imagination and Creativity Reshaped Human Evolution Evolution of Beauty – Genetics Talk by Richard PrumWhy have animals evolved a sense of beauty?The Neuroscience of BeautyWe may have the evolution of beauty completely wrongBook The Evolution of Beauty by Richard O. Prum How Darwin’s […]

Misconceptions about Autonomous Systems

Following are notes from several research papers on autonomy. The Pentagon, or U.S. Department of Defense, says several factors impede the deployment and adoption of autonomous systems: In the absence of an adequately high level of autonomy that can be relied upon, substantial operator involvement is required, which not only severely limits operational gains but […]

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 […]

The future of computer architectures

This is a lecture given by John Hennessy and David Patterson at the ACM Turing Award. They offer their vision of addressing Moore’s law slowdown via heterogeneous computer architectures and hardware/software codesign. Quantum computers are on the same schedule as fusion. All exponentials eventually end. ‒ Gordon Moore Titled “A New Golden Age for Computer […]

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 […]

What Makes Us Human?

This entire post is dedicated to consciousness and secrets of the brain and mind. The most interesting talk here is by Stuart Hameroff. What Makes Us Human? Faith, Fantasy, and the Big Questions in Modern Physics Is Quantum Physics Necessary for the Account of Consciousness? Cartographers of the Brain: Mapping the Connectome Wiring up the […]
