Quantum cryptography is hacked

Just in case you believed there was a system that could not be cracked.

Quantum cryptography uses the laws of quantum mechanics to encode data securely. Most researchers consider such quantum networks to be nearly 100% uncrackable. But a group from the Massachusetts Institute of Technology (MIT) in Cambridge was able to 'listen in' using a sort of quantum-mechanical wiretap. The trick allowed them to tease out about half of the data, in a way that couldn't be detected by those transmitting or receiving the message.

If it's human made, then it can be cracked...by another human.
