Analytic solution to degenerate biphoton states generated in arrays of nonlinear waveguides
Jefferson Delgado-Quesada, David Barral, Kamel Bencheikh +1
The arrays of nonlinear waveguides are a powerful integrated photonics platform for studying and manipulating quantum states of light. Also, they are a valuable resource for variou…
Diverse Entanglement Mechanisms in Multimode Nonlinear Continuous Variables
Da Zhang, David Barral, Yanpeng Zhang +1
Non-Gaussian entangled states play a crucial role in harnessing quantum advantage in continuous-variable quantum information. However, how to fully characterize N-partite (N > 3) n…
Ultra-sensitive separation estimation of optical sources
Clémentine Rouvière, David Barral, Antonin Grateau +4
Historically, the resolution of optical imaging systems was dictated by diffraction, and the Rayleigh criterion was long considered an unsurpassable limit. In superresolution micro…
Correlated twin-photon generation in a silicon nitrite loaded thin film PPLN waveguide
Antoine Henry, David Barral, Isabelle Zaquine +4
Photon-pair sources based on thin film lithium niobate on insulator technology have a great potential for integrated optical quantum information processing. We report on such a sou…
Hierarchy of Genuine Tripartite Non-Gaussian Entanglement
Da Zhang, David Barral, Yanpeng Zhang +2
Triple-photon states generated by three-mode spontaneous parametric down-conversion are the paradigm of unconditional non-Gaussian states, essential assets for quantum advantage. H…
Hierarchy of Nonlinear Entanglement Dynamics for Continuous Variables
Da Zhang, David Barral, Yin Cai +3
The entanglement produced by a bilinear Hamiltonian in continuous variables has been thoroughly studied and widely used. In contrast, the physics of entanglement resulting from non…
