    "abstract": "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 of this type, for which we find the density matrices\navailable to the eavesdropper and the optimal information which can be\nextracted from them. We prove security against this attack and discuss security\nagainst any attack allowed by the rules of quantum mechanics.",
