MagiQ has now started commercial shipments
of its quantum cryptography systems, which it claims is the first
commercially available device of its type.
Quantum cryptography goes a step further than electronic cryptography through
its employment of a stream of photons, the quantum properties of which
determine the key. The fun part is that if an intruder observes or
intercepts the transmission, those properties get changed.
Slashdot covers it.
