    "abstract": "We propose efficient-phase-encoding protocols for continuous-variable quantum\nkey distribution using coherent states and postselection. By these phase\nencodings, the probability of basis mismatch is reduced and total efficiency is\nincreased. We also propose mixed-state protocols by omitting a part of\nclassical communication steps in the efficient-phase-encoding protocols. The\nomission implies a reduction of information to an eavesdropper and possibly\nenhances the security of the protocols. We investigate the security of the\nprotocols against individual beam splitting attack.",
