Abstract

We compare the performance of various quantum-key-distribution (QKD) systems using 1550 nm up-conversion single-photon detectors. The analysis is based on the error rate and the secure communication rate as a function of distance for three QKD protocols: the Bennett-Brassard 1984, the Beruiett-Brassard-Vlerinin 1992, and the coherent differential-phase-shift keying (DPSK) protocols. We discussed that the security of DPSK protocol against any type of individual photon splitting attack and concluded that the simple and efficient DPSK protocol allows for more than 200 km of secure communication distance with high communication rates.
