Improving Short-Term Stability in Optical Lattice Clocks by Quantum Nondemolition Measurements
Daniel Benedicto Orenes, Robert J. Sewell, Jérôme Lodewyck +1
We propose a multimeasurement estimation protocol for Quantum Nondemolition (QND) measurements in a Rabi clock interferometer. The method is well suited for current state-of-the-ar…
The Space Optical Clocks Project: Development of high-performance transportable and breadboard optical clocks and advanced subsystems
S. Schiller, A. Görlitz, A. Nevsky +28
The use of ultra-precise optical clocks in space ("master clocks") will allow for a range of new applications in the fields of fundamental physics (tests of Einstein's theory of Ge…
Non-destructive measurement of the transition probability in a Sr optical lattice clock
Jerome Lodewyck, Philip G. Westergaard, Pierre Lemonde
We present the experimental demonstration of non-destructive probing of the 1S0-3P0 clock transition probability in an optical lattice clock with 87Sr atoms. It is based on the pha…
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…
Tight bound on coherent states quantum key distribution with heterodyne detection
Jerome Lodewyck, Philippe Grangier
We propose a new upper bound for the eavesdropper's information in the direct and reverse reconciliated coherent states quantum key distribution protocols with heterodyne detection…
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…
