    "abstract": "A generalization of the quantum cryptographic protocol by Bennett and\nBrassard is discussed, using three conjugate bases, i.e. six states. By\ncalculating the optimal mutual information between sender and eavesdropper it\nis shown that this scheme is safer against eavesdropping on single qubits than\nthe one based on two conjugate bases. We also address the question for a\nconnection between the maximal classical correlation in a generalized Bell\ninequality and the intersection of mutual informations between sender/receiver\nand sender/eavesdropper.",
