After NSA leaks, businesses seek security in quantum physics

Cryptography is having a rough few months. On September 5th, leaked NSA documents revealed a systematic effort by the agency to undermine encrypted communications across the board, breaking accepted standards like SSL and systematically weakening others. But while the news has been unsettling for math-based cryptography, it's fueled interest in less conventional means of secure communication, particularly a fiber-optic technique called "quantum cryptography" that uses the properties of light to fend off would-be wiretappers. ...
