"ALGORITHMS: Encryption technology makes quantum leap"

Using a superconducting detector, the National Institute of Standards and Technology has set a new world's distance record in quantum-key distribution--an uncrackable encryption technology that ensures absolute security by harnessing the quantum-physics principle that observations affect outcome. Until last week, Toshiba Research Europe Ltd. and Cambridge Research Laboratory held the record for the most sensitive detector with a prototype system that stretched 75 miles. Now NIST has upped the ante by more than 50 percent, reporting last week that it had transmitted over nearly 115 miles.
