A New Cryptography Uses the Quirks of Photon Streams
By JOHN MARKOFF
he quirky world of quantum physics, where mathematical elements can
hold multiple values and objects can be in several places at once,
is heading toward commercial products.
A start-up company, MagiQ Technologies, plans to announce today a
cryptogaphy or code system that uses a technology called quantum key
distribution to thwart eavesdropping on a fiber optic communication
channel. The company, based in New York, says it has a working model of
its system and will have a commercial version available in the second
half of next year.
