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…

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…
