Abstract

We experimentally demonstrates a two way quantum key distribution (QKD) system with a single Mach Zehnder interferometer over 10 km standard grade optical fiber. The scheme utilizes optical phase encoding/decoding with polarization of photon maintained through the use of polarization maintaining optical fiber at the transmitting and receiving ends and achieves a visibility of 99%.
