Abstract

The problem of communication using optical coherent quantum states, in the presence of background radiation, is considered. Two modulation formats are studied, ON-OFF keying (OOK) and M-ary pulse-position modulation (PPM). The bit-error-rate performance improvement due to low-density parity-check coding is reported. For OOK, it is assumed that the coherent state signal has a random phase. For an average number of noise photons N=0.1, the required number of signal photons per information bit is six in the case of coded quantum OOK. For the same level of noise (N=0.1) and assuming that signal phase is known, coded 16-ary PPM requires only 1.21 of signal photons per information bit.
