    "abstract": "We analyze various eavesdropping strategies on a quantum cryptographic\nchannel. We present the optimal strategy for an eavesdropper restricted to a\ntwo-dimensional probe, interacting on-line with each transmitted signal. The\nlink between safety of the transmission and the violation of Bell\u0027s inequality\nis discussed. We also use a quantum copying machine for eavesdropping and for\nbroadcasting quantum information.",
