    "abstract": "We propose a protocol for deterministic communication that does not make use\nof entanglement. It exploits nonorthogonal states in a two-way quantum channel\nattaining significant improvement of security and efficiency over already known\ncryptographic protocols. The presented scheme, being deterministic, can be\ndevoted to direct communication as well as to key distribution, and its\nexperimental realization is feasible with present day technology.",
