SECOQC White Paper on Quantum Key Distribution and Cryptography (2007)
Alleaume, Romain, Bouda, Jan, Branciard, Cyril, Debuisschert, Thierry, Dianati, Mehrdad, Gisin, Nicolas, ...
The SECOQC White Paper on Quantum Key Distribution and Cryptography is the outcome on a thorough consultation and discussion among the participants of the European project SECOQC (www.secoqc.net)....
ASIC for High-Speed-Gating and Free Running Operation of SPADs (2007)
Rochas, Alexis, Guillaume-Gentil, Christophe, Gautier, Jean-Daniel, Pauchard, Alexandre, Ribordy, Gregoire;, Zbinden, Hugo, ...
Single photon detection at telecom wavelengths is of importance in many industrial applications ranging from quantum cryptography, quantum optics, optical time domain reflectometry, non-invasive...
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...
Scarani, Valerio, Acin, Antonio, Ribordy, Gregoire, Gisin, Nicolas
We introduce a new class of quantum quantum key distribution protocols, tailored to be robust against photon number splitting (PNS) attacks. We study one of these protocols, which differs from the...
Quantum cloning with an optical fiber amplifier (2002)
Fasel, Sylvain, Gisin, Nicolas, Ribordy, Gregoire, Scarani, Valerio, Zbinden, Hugo
It has been shown theoretically that a light amplifier working on the physical principle of stimulated emission should achieve optimal quantum cloning of the polarization state of light. We...
Long distance entanglement based quantum key distribution (2000)
Ribordy, Gregoire, Brendel, Juergen, Gautier, Jean-Daniel, Gisin, Nicolas, Zbinden, Hugo
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 distance transmission....
Fast and User-friendly Quantum Key Distribution (1999)
Ribordy, Gregoire, Gautier, Jean-Daniel, Gisin, Nicolas, Guinnard, Olivier, Zbinden, Hugo
Some guidelines for the comparison of different quantum key distribution experiments are proposed. An improved 'plug & play' interferometric system allowing fast key exchange is then introduced....
