摘要：

An optimum quantum receiver which has a negligible probability of detection error is proposed for a binary signal in quantum communication systems. The quantum measurement that optimally distinguishes between two nonorthogonal quantum states and the signal retransmission method used in the conventional digital communication are applied.
