Abstract

We propose a unidirectional quantum key distribution (QKD) system based upon a time-division Mach-Zehnder interferometer (MZ) using phase stabilized optical fibers (PSOFs) for the sake of achieving the phase stability during the key distribution. A simple comparison between MZs constituent with PSOF and normal single mode fiber (SMF) is made. During the key distribution over 25km of standard optical fiber, the phase drift of 4.6 × 10^-4π/s is obtained. We discuss the demonstration of the quantum key distribution when the asymmetric MZ (AMZ) of PSOF is applied on the proposed QKD system.
