Quantum trickery could lead to stealth radar - tech - 31 March 2011 - New Scientist: "STEALTHY radar systems and the ability to transmit large amounts of data over long distances are a step closer thanks to a technique that could improve the efficiency of modern optics by a factor of 1000.
Traditional methods of transmitting data, such as fibre optics or laser-based radar, require roughly 100 photons to transmit a single bit of data. Now a team led by Saikat Guha at Raytheon BBN Technologies in Cambridge, Massachusetts, say they can transmit 10 bits on a single photon - a 1000-fold improvement."
