the quantum encryption in this article still suffers from 'man in the middle attacks'. I think the idea the security people have in mind is the message is destroyed once you read it, but theres no stopping someone from reading the message and resending it. this technique adds little to security. a determined hacker will find it harder to break regular encryption anyway. i think it will amount to the hacker sighing and muttering ' dammit i have to get out the repeater again'
p.s.
quantum computing can decrypt encrypted messages in use today instantly - from what I heard elsewhere.
