Calling quantum hackers

NY Times: "The 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 cryptography or code system that uses a technology called quantum key distribution to thwart eavesdropping on a fiber optic communication channel."

"A limit of the system is that it would not work on the Internet, only over dedicated fiber cables in which the photon transmission can be carefully controlled. But outside researchers say that quantum cryptography does make possible electronic conversations that would be immune to eavesdropping. Industry analysts say that military applications would probably be the primary use for quantum cryptography."
