Improvement of continuous-variable quantum key distribution systems by using optical preamplifiers
Simon Fossier, Eleni Diamanti, Thierry Debuisschert +2
Continuous-variable quantum key distribution protocols, based on Gaussian modulation of the quadratures of coherent states, have been implemented in recent experiments. A present l…
Field test of a continuous-variable quantum key distribution prototype
Simon Fossier, Eleni Diamanti, Thierry Debuisschert +3
We have designed and realized a prototype that implements a continuous-variable quantum key distribution protocol based on coherent states and reverse reconciliation. The system us…
Quantum key distribution over 25 km with an all-fiber continuous-variable system
Jerome Lodewyck, Matthieu Bloch, Raul Garcia-Patron +8
We report on the implementation of a reverse-reconciliated coherent-state continuous-variable quantum key distribution system, with which we generated secret keys at a rate of more…
Experimental implementation of non-Gaussian attacks on a continuous-variable quantum key distribution system
Jerome Lodewyck, Thierry Debuisschert, Raul Garcia-Patron +3
An intercept-resend attack on a continuous-variable quantum-key-distribution protocol is investigated experimentally. By varying the interception fraction, one can implement a fami…
Increasing entanglement between Gaussian states by coherent photon subtraction
Alexei Ourjoumtsev, Aurelien Dantan, Rosa Tualle-Brouri +1
We experimentally demonstrate that the entanglement between Gaussian entangled states can be increased by non-Gaussian operations. Coherent subtraction of single photons from Gauss…
Quantum homodyne tomography of a two-photon Fock state
Alexei Ourjoumtsev, Rosa Tualle-Brouri, Philippe Grangier
We present a continuous-variable experimental analysis of a two-photon Fock state of free-propagating light. This state is obtained from a pulsed non-degenerate parametric amplifie…
