PY - 2009 DA - 2009// TI - High rate long-distance quantum key distribution over 250 km of ultra low loss fibres JO - New J. Phys. SP - 075003 VL - 11 IS - 7 KW - SSPD KW - quantum cryptography KW - QKD KW - COW AB - We present a fully automated quantum key distribution prototype running at 625 MHz clock rate. Taking advantage of ultra low loss fibres and low-noise superconducting detectors, we can distribute 6,000 secret bits per second over 100 km and 15 bits per second over 250km.
