Comprehensive Characterization of InGaAs/InP Avalanche Photodiodes at 1550 nm with an Active Quenching ASIC
Jun Zhang, Rob Thew, Jean-Daniel Gautier +2
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 detect…
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…
Approaches to Single Photon Detection
R. T. Thew, N. Curtz, P. Eraerds +6
We present recent results on our development of single photon detectors, including: gated and free-running InGaAs/InP avalanche photodiodes; hybrid detection systems based on sum-f…
Free-running InGaAs/InP Avalanche Photodiode with Active Quenching for Single Photon Counting at Telecom Wavelengths
R. T. Thew, D. Stucki, J-D. Gautier +2
We present an InGaAs/InP avalanche photodiode with an active quenching circuit on an ASIC (application specific integrated circuit) that is capable of operating in both gated and f…
Long distance entanglement based quantum key distribution
Gregoire Ribordy, Juergen Brendel, Jean-Daniel Gautier +2
A detailled analysis of quantum key distribution employing entangled states is presented. We tested a system based on photon pairs entangled in energy-time optimized for long dista…
Fast and User-friendly Quantum Key Distribution
Gregoire Ribordy, Jean-Daniel Gautier, Nicolas Gisin +2
Some guidelines for the comparison of different quantum key distribution experiments are proposed. An improved 'plug & play' interferometric system allowing fast key exchange is th…
