Heisenberg-limited eavesdropping on the continuous-variable quantum cryptographic protocol with no basis switching is impossible
J. Sudjana, L. Magnin, R. Garcia-Patron +1
The Gaussian quantum key distribution protocol based on coherent states and heterodyne detection [Phys. Rev. Lett. 93, 170504 (2004)] has the advantage that no active random basis…
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…
