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…
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…
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…
