A method for characterizing coherent-state quantum gates
Rémi Blandino, Franck Ferreyrol, Marco Barbieri +2
We discuss and implement experimentally a method for characterizing quantum gates operating on superpositions of coherent states. The peculiarity of this encoding of qubits is to w…
Non-Gaussianity of quantum states: an experimental test on single-photon added coherent states
Marco Barbieri, Nicolò Spagnolo, Marco G. Genoni +5
Non Gaussian states and processes are useful resources in quantum information with continuous variables. An experimentally accessible criterion has been proposed to measure the deg…
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…
