Commercial quantum cryptography

In light of recent discussions about the future of cryptography, and speculations about the book Cryptonomicon, this recent article from The Economist speaks on the first commercial system for quantum cryptography. An excerpt:

MagiQ is in the final stages of testing a system for quantum cryptography, which it plans to release commercially within the next few months. Encryption engineers have long waxed lyrical about quantum cryptography, but this is among the very first commercial implementations. The advantage of quantum cryptography schemes is that the code they generate are simply not?even in theory?breakable.
