<p>According to Physics World researchers at the University of Bristol, UK have made a prototype optical quantum computer chip and used it to perform a mathematical calculation. The device consists of tiny silica waveguides on a silicon chip and carries out a version of the quantum calculation known as Shor's algorithm. The result is an important step towards making practical, real-world quantum computers.</p>

Applications are invited for a Chair in Theoretical Quantum Optics / Quantum Information Science. The post is available from 1st January 2010 and is based in the Quantum Optics and Laser Science (QOLS) Group of the Department of Physics.

New results in quantum cryptography show that the original protocol based on Bell's inequality is so powerful that it extends beyond the quantum realm. In the recent issue of Physics World Artur Ekert traces it all back to Einstein's considerations about physical reality.

Post-Doctoral fellowships at the Institute for Quantum Computing

The Institute for Quantum Computing is inviting applications for postdoctoral positions in all aspects of quantum information processing, bridging areas from fundamental theory to physical implementations.

Researchers in Austria, Germany and the US, proposed a scheme to couple the motion of a single atom with a crystal membrane. This scheme could be used to observe quantum-mechanical effects on a larger scale than ever before.
