At the end of a recent discussion (in the comments to this post), Allen and I started to discuss whether quantum computing theory had something to say about the potential for simulating the human mind on a computer. I then read a couple of review articles on quantum computing he referenced. Before g...

The future of computing was under the spotlight at the Institute of Physics’ Condensed Matter and Materials Physics conference at the Royal Holloway College of the University of London on 26-28 March. The end of the silicon chip The silicon chip, which has supplied several decades’ worth...

A team of physicists and engineers has demonstrated exquisite control of single particles of light — photons — on a silicon chip to make a major advance towards the long sought after goal of a super-powerful quantum computer. Dr Jeremy O’Brien, his PhD student Alberto Politi, and t...
