Multimode quantum properties of a self-imaging OPO: squeezed vacuum and EPR beams generation
L. Lopez, Benoît Chalopin, Arnaud Rivière De La Souchère +3
We investigate the spatial quantum properties of the light emitted by a perfectly spatially degenerate optical parametric oscillator (self-imaging OPO). We show that this device pr…
Spatial multimode entanglement within one laser beam
J. Janousek, K. Wagner, J-F. Morizur +4
Optical entanglement is a key requirement for many quantum communication protocols. Conventionally entanglement is formed between two distinct beams, with the quantum correlations…
Quantum improvement of time transfer between remote clocks
Brahim Lamine, Claude Fabre, Nicolas Treps
Exchanging light pulses to perform accurate space-time positioning is a paradigmatic issue of physics. It is ultimately limited by the quantum nature of light, which introduces flu…
Experimental demonstration of frequency-degenerate bright EPR beams with a self-phase-locked optical parametric oscillator
Gaelle Keller, Virginia D'Auria, Nicolas Treps +3
We report the first experimental observation of bright EPR beams produced by a type-II optical parametric oscillator operating above threshold at frequency degeneracy. The degenera…
