Quantum cryptography hacked

Instead of posting about the number of the week, I think it's more interesting to post that quantum cryptography has been hacked.

More precisely, wiretrapped (near 40% of information was sniffed). It was a scientific test and would probably fail and be detected (sooner or later it disrupts the communication and creates an anomaly spike in the signal), but as scientists were able to delay that unwanted spike (until they tried obtaining more than 40% of info correctly), proofs that security measures have to be developed to avoid future problems.
