Abstract(in English) | A high-speed quantum key distribution system was developed with the wavelength-division multiplexing (WDM) technique and dedicated key distillation hardware engines. Two interferometers for encoding and decoding are shared over eight wavelengths to reduce the system's size, cost, and control complexity. The key distillation engines can process a huge amount of data from the WDM channels by using a 1-Mbit block in real time. We demonstrated a 3-channel WDM system that simultaneously uses avalanche photodiodes and superconducting single photon detectors. We achieved 12-hour continuous key generation with a secure key rate of 208 kbps through a 45-km field fiber with 14.5-dB loss. |
