Security of Quantum Cryptography against Collective Attacks
We present strong attacks against quantum key distribution schemes which use\nquantum memories and quantum gates to attack directly the final key. We analyze\na specific attack ...

In this paper we use properties of quantum mixed states to find bounds on various measures of their distinguishability. These bounds are used for analyzing strong joint attacks ...
