Quantum correlations versus Multisimultaneity: an experimental test
Andre Stefanov, Nicolas Gisin, Antoine Suarez +1
Multisimultaneity is a causal model of relativistic quantum physics which assigns a real time ordering to any set of events, much in the spirit of the pilot-wave picture. Contrary…
PPLN Waveguide for Quantum Communication
S. Tanzilli, H. de Riedmatten, W. Tittel +5
We report on energy-time and time-bin entangled photon-pair sources based on a periodically poled lithium niobate (PPLN) waveguide. Degenerate twin photons at 1314 nm wavelength ar…
Photon counting for quantum key distribution with Peltier cooled InGaAs/InP APD's
Damien Stucki, Grégoire Ribordy, André Stefanov +3
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 y…
Faint laser quantum key distribution: Eavesdropping exploiting multiphoton pulses
Stephane Felix, Nicolas Gisin, Andre Stefanov +1
The technological possibilities of a realistic eavesdropper are discussed. Two eavesdropping strategies taking profit of multiphoton pulses in faint laser QKD are presented. We con…
