TL;DR: In this article, the authors presented a fibre-optical quantum key distribution system based on the plug-and-play set-up, which works at 1550nm and is tested under field conditions using aerial and terrestrial cables and performed key exchange over 67 km between Geneva and Lausanne.

TL;DR: In this article, a physical random number generator based on the intrinsic randomness of quantum mechanics is described, where the random events are realized by the choice of single photons between the two outputs of a beam splitter.

TL;DR: In this paper, an improved plug-and-play interferometric system for quantum key distribution is presented, where self-alignment and compensation of birefringence remain, while limitations due to reflections are overcome.

TL;DR: InGaAs/InP avalanche photodiodes operated in the so-called Geiger mode currently represent the best solution to detect single-photon beyond 900nm as mentioned in this paper.

TL;DR: A compactly integrated, 625 MHz clocked coherent one-way quantum key distribution system which continuously distributes secret keys over an optical fibre link is presented and a fast hardware key distillation engine is implemented which allows for high secret key rates up to 4 Mbps in real time.
