Feynman would have approved

Astute followers of this blog know that quantum computing was the brain child of Richard Feynman whose contribution to the quantum field theory of electrodynamics earned him a Nobel prize. Feynman was the first to remark on the fact that classical computers … Continue reading

Quantum Computing – So what is it good for? – Updated below

If anybody in the wider IT community has heard about Quantum Computing, it’s usually in the context of how it may obliterate our current industry standard encryption (e.g. RSA). Probably Peter Shore didn’t realize that he was about to define the … Continue reading

SUSY Matrix Blues

Dr. Gates, a distinguished theoretical physicist (with a truly inspiring biography), recently made an astounding statement during an interview on NPR (the clip from the On Being show can be found here – a transcript is also online).  It gave … Continue reading

A Picture is Worth More Than a Thousand Lines of Code

Imagine a world before the advent of the steam engine that nevertheless imminently anticipates this marvelous machine’s arrival. Although no locomotive has been built, civil engineers are already busy discussing how to build rail-road bridges, architects try to determine the optimal layout of train stations, and the logistics … Continue reading

About Time – Blogroll Memory Hole Rescue

One of the most fascinating aspects of quantum information research is that it sheds light on the connections between informational and thermodynamic entropy, as well as how time factors into quantum dynamics. I.e. Schroedinger Equation and Heisenberg picture are equivalent. … Continue reading

Analog VLSI for Neural Networks – A Cautious Tale for Adiabatic Quantum Computing

Fifteen years ago I attempted to find an efficient randomized training algorithm for simple artificial neural networks suitable for implementation on a specialized hardware chip. The latter’s design only allowed feed-forward connections i.e. back-propagation on the chip was not an option.  The idea … Continue reading

A Brief History of Quantum Computing

An attempted apotheosis. In the beginning there was Feynman.  And Feynman was with the scientific establishment.  Feynman was a god. Or at least as close to it as a mortal physicist can ever be. He tamed the light with his QED … Continue reading
