Abstract

In this paper, a signal transmission and decision system in which an event of occurrence of decision error caused by the quantum noise can be detected is presented. The system is, in principle, constituted on the basis of a binary polarization-shift keying (PolSK) signal. Using retransmission technology for the error detection system, the decision error probability can be suppressed to 0. The binary PolSK system uses two polarization channels, and then the system has redundancy on channel efficiency. A more efficient signal system which uses only one polarization channel and is based on the binary phase-shift keying (PSK) signal is presented
