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...
Fast and simple one-way Quantum Key Distribution (2005)
Stucki, Damien, Brunner, Nicolas, Gisin, Nicolas, Scarani, Valerio, Zbinden, Hugo
We present and demonstrate a new protocol for practical quantum cryptography, tailored for an implementation with weak coherent pulses to obtain a high key generation rate. The key is obtained by a...
A Fabry-Perot like two-photon interferometer for high-dimensional time-bin entanglement (2005)
Stucki, Damien, Zbinden, Hugo, Gisin, Nicolas
We generate high-dimensional time-bin entanglement using a mode-locked laser and analyze it with a 2-photon Fabry-Perot interferometer. The dimension of the entangled state is limited only by the...
Towards practical and fast Quantum Cryptography (2004)
Gisin, Nicolas, Ribordy, Gregoire, Zbinden, Hugo, Stucki, Damien, Brunner, Nicolas, Scarani, Valerio
We present a new protocol for practical quantum cryptography, tailored for an implementation with weak coherent pulses. The key is obtained by a very simple time-of-arrival measurement on the data...
Photon counting for quantum key distribution with Peltier cooled InGaAs/InP APD's (2001)
Stucki, Damien, Ribordy, Grégoire, Stefanov, André, Zbinden, Hugo, Rarity, John G., Wall, Tom
The performance of three types of InGaAs/InP avalanche photodiodes is investigated for photon counting at 1550 nm in the temperature range of thermoelectric cooling. The best one yields a dark count...
