Versatile photonic entanglement synthesizer in the spatial domain
David Barral, Mattia Walschaers, Kamel Bencheikh +4
Multimode entanglement is an essential resource for quantum information in continuous-variable systems. Light-based quantum technologies will arguably not be built upon table-top b…
Exact results for nonequilibrium dynamics in Wigner phase space
Kamel Bencheikh, Luis M. Nieto
We study time evolution of Wigner function of an initially interacting one-dimensional quantum gas following the switch-off of the interactions. For the scenario where at the…
Coupling quasi-phase matching: entanglement buildup in nonlinear waveguide arrays
David Barral, Nadia Belabas, Kamel Bencheikh +1
Wavevector quasi-phase matching was devised in the 1960s as a way to boost nonlinear interactions with efficient quantum noise squeezing as one outstanding outcome. In the era of q…
Photonic crystal nanobeam cavities with optical resonances around 800 nm
Ivens Saber, Rajiv Boddeda, Fabrice Raineri +7
We report on the design and the fabrication of 1D photonic crystal (PhC) nanobeam cavities with optical resonances around 800 nm, compatible with Rubidium, Cesium or Argon atomic t…
Zero supermode-based multipartite entanglement in nonlinear waveguides arrays
David Barral, Kamel Bencheikh, Nadia Belabas +1
We show that arrays of nonlinear waveguides in the second harmonic generation regime are a promising source of continuous-variable entanglement. We indeed demonstrate ana…
Symmetry-based analytical solutions to the χ^{(2)} nonlinear directional coupler
David Barral, Kamel Bencheikh, Peter J. Olver +2
In general the ubiquitous χ^{(2)} nonlinear directional coupler, where nonlinearity and evanescent coupling are intertwined, is nonintegrable. We rigorously demonstrate that matchi…
