maintenance free operation of wdm quantum key distribution system through a Field Fiber over 30 days
Optics Express, 2013Co-Authors: Kenichiro Yoshino, Mikio Fujiwara, Masahide Sasaki, Takao Ochi, Akio TajimaAbstract:Maintenance-free wavelength-division-multiplexing quantum key distribution for 30 days was achieved through a 22-km Field Fiber. Using polarization-independent interferometers and stabilization techniques, we attained a quantum bit error rate as low as 1.70% and an estimated secure key rate as high as 112.4 kbps for a record-breaking 291.3 Gbits of estimated secure keys accumulated over an uninterrupted operation period.

high speed wavelength division multiplexing quantum key distribution system
Optics Letters, 2012Co-Authors: Kenichiro Yoshino, Akihiro Tanaka, Mikio Fujiwara, Seigo Takahashi, Yoshihiro Nambu, Akihisa Tomita, Shigehito Miki, Taro Yamashita, Zhen Wang, Masahide SasakiAbstract: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 three-channel WDM system that simultaneously uses avalanche photodiodes and superconducting single-photon detectors. We achieved 12 h continuous key generation with a secure key rate of 208 kilobits per second through a 45 km Field Fiber with 14.5 dB loss.
