Practical fast gate rate InGaAs/InP single-photon avalanche photodiodes (2009)
Zhang, Jun, Thew, Rob, Barreiro, Claudio, Zbinden, Hugo
We present a practical and easy-to-implement method for high-speed near infrared single-photon detection based on InGaAs/InP single-photon avalanche photodiodes (SPADs), combining aspects of both...

We present an active quenching application specific integrated circuit (ASIC), for use in conjunction with InGaAs/InP avalanche photodiodes (APDs), for 1550 nm single-photon detection. To evaluate...
High speed coherent one-way quantum key distribution prototype (2008)
Stucki, Damien, Barreiro, Claudio, Fasel, Sylvain, Gautier, Jean-Daniel, Gay, Olivier, Gisin, Nicolas, ...
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 capable of...

We implement a photon-counting Optical Time Domain Reflectometer (OTDR) at 1.55um which exhibits a high 2-point resolution and a high accuracy. It is based on a low temporal-jitter photon-counting...
Quantum communication, and indeed quantum information in general, has changed the way we think about quantum physics. In 1984 and 1991, the first protocol for quantum cryptography and the first...
