Quantum Cryptography Hacked

[vee_ess]

A team of researchers has, for the first time, hacked into a network protected by quantum encryption. 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. More info can be found at Nature.com.
