Researchers unite to distribute quantum keysComputer securityResearchers from across Europe have united to build the largest quantum key distribution network ever built. The efforts of 41 research and industrial organisations were realised as secure, quantum encrypted information was sent over an eight node, mesh network.

Quantum Physicists at UCSB have made a scientific breakthrough by controlling particles of light. (Monday, June 1, 2009) Physicists Max Hofheinz, Haohua Wang, John Martinis and Andrew Cleland trapped photons in a qubit, sometimes called an “artificial atom,” and were able to control it in order to create a superposition of states - where multiple states of photons exist simultaneously.

Quantum cryptography hits the fast lane (18th May 2009)
Scientists at Toshiba Research Europe in Cambridge, UK, are claiming a
significant step forward in the race to make quantum cryptography a
practical ...previous key rates of 10 kbit/s over 20 km and 10 bit/s over 100 km
were not sufficient for this purpose. The Toshiba team demonstrated a
key rate of 1 Mbit/s over 20 km.
