First-Ever Quantum Calculation

Researchers at the University of Queensland have made the very first execution of a quantum calculation. By manipulating entangled photons, they calculated the prime factors of the number 15.

In addition to being a major step towards building the first quantum computers, this breakthrough is of interest because it could potentially be used to break the kinds of strong encryption that elude conventional computers.

  1. The use of quantum boxes as encryption breakers is discussed at some length in Stross’ new novel HALTING STATE, which you mentioned several weeks ago ON THIS VERY BLOG!

    Having now read the book, I can agree with the reviews linked to the blog. This is a *very strong novel*, despite a plot that nearly requires a quantum computer to decrypt. The epilogue actually made me laugh out loud.
