摘要

Recent developments in Quantum Key Distribution (QKD) system are reviewed. A high sensitivity photon detector combining the two avalanche photon diodes (APD) has been demonstrated for qubit discrimination in 1,550nm. A stable interferometer on a planer light-wave circuit (PLC) has been developed. Single-photon interference over 150km has been achieved as a result of the above improvements. A temperature insensible QKD system is being developed for high speed (100kbps) key transmission over a 40km fiber.
