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 -- an unavoidable principle of quantum mechanics -- meaning the sender and receiver can tell if anyone is eavesdropping.
