A fast and versatile QKD system with hardware key distillation and wavelength multiplexing
Nino Walenta, Andreas Burg, Dario Caselunghe +17
We present a 625 MHz clocked coherent one-way quantum key distribution (QKD) system which continuously distributes secret keys over an optical fibre link. To support high secret ke…

High rate, long-distance quantum key distribution over 250km of ultra low loss fibres
D. Stucki, N. Walenta, F. Vannel +6
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…

High speed coherent one-way quantum key distribution prototype
Damien Stucki, Claudio Barreiro, Sylvain Fasel +8
We report the first real world implementation of a Quantum Key Distribution (QKD) system over a 43dB-loss transmission line in the Swisscom fibre optic network. The QKD system is c…
