New paper: Optical quantum computing with photons of arbitrarily low fidelity and purity

Download full text here. Linear optics quantum computing (LOQC) is a leading candidate for the implementation of large scale quantum computers. Here quantum information is encoded into the quantum states of light and computation proceeds via a linear optics network. It is well known that in such schemes there are stringent requirements on the spatio-temporal […]

Many worlds and the interpretation of quantum mechanics

This post is on quantum mechanics, but is intended to be understandable by anyone. The small amount of mathematical notation that I introduce should be fairly digestible to anyone without a physics background. A couple of nights ago I had a dinner table conversation with a fellow physicist, who raised the highly emotive, almost religious […]

Thanks Bob

Recently, on behalf of a group of concerned Australian scientists, I sent a letter to the Australian Foreign Minister and Shadow Foreign Minister regarding the plight of a young Iranian physicist who was imprisoned in Iran for “communicating with a hostile government” (read the letter here). Today I received a personally signed letter from the […]

Open letter to the Australian Christian Lobby

This is my open letter to Jim Wallace, managing director of the Australian Christian Lobby. Please share this letter via social media. Dear Mr. Wallace, In the last year the ACL has released significantly more statements on homosexuality than on all other social issues combined. This bias brings into question the agenda of the ACL […]

Do we need quantum cryptography?

Quantum cryptography is all the hype. Everyone’s talking about it. Scientists are competing to do it over the longest possible distances, with the highest possible bit-rates and even to put it into orbit on satellites. In this post I’d like to explain what quantum cryptography is and compare it to classical cryptography. Then I’ll tell […]

The Loch Ness monster

Now tax-payer funded schools in the US are educating children that the Loch Ness monster is real… as a way of disproving Darwinism. See here.
