Direct and Reverse Secret-Key Capacities of a Quantum Channel
Stefano Pirandola, Raul Garcia-Patron, Samuel L. Braunstein +1
We define the direct and reverse secret-key capacities of a memoryless quantum channel as the optimal rates that entanglement-based quantum key distribution protocols can reach by…
Continuous-variable quantum key distribution protocols over noisy channels
Raul Garcia-Patron, Nicolas J. Cerf
A continuous-variable quantum key distribution protocol based on squeezed states and heterodyne detection is introduced and shown to attain higher secret key rates over a noisy lin…
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…
Unconditional optimality of Gaussian attacks against continuous-variable QKD
Raul Garcia-Patron, Nicolas J. Cerf
A fully general approach to the security analysis of continuous-variable quantum key distribution (CV-QKD) is presented. Provided that the quantum channel is estimated via the cova…
