Not surprisingly, it's attacking the implementation, not the physics --
but of course we use implementations to communicate, rather than
theories.
A failure in implementation leads to the ability to eavesdrop on a
quantum-secrecy based key exchange on 2/3 of the types of quantum
equipment used.

resource on quantum crypto.
