文摘

The quantum key distribution (QKD) in quantum communications service has recently become the major area of research, because of its potential features to provide secured mode communication system. In this paper, we investigate the ability of quantum networks to support both random and non-random data traffic single-photon quantum communications signals on a shared infrastructure. The effect of wave length on distance coverage with the quantum bit error rate of a QKD system is increasing. The results of random phase showed minimal distance coverage over non-random phase. For fluctuating amplitude of random show a change in system performance improved sending capabilities. Hence, it is found that rare fluctuations should not degrade system performance significantly, but the data sending mode has a significant effect on channel integrity.
