Résumé
In this talk I will present the research I carried out along the last few years as postdoc at the Centre de Nanosciences et de Nanotechnologies (C2N, Université Paris-Saclay). I will start introducing basic concepts of quantum optics, continuous variables, quantum information and integrated optics. Then I will talk about coupled nonlinear waveguides as a source of Gaussian entangled states of light, and how to tailor this entanglement to produce continuous-variable cluster states with interest in quantum computing. Finally, I will introduce a class of unconditional non-Gaussian states recenlty demonstrated experimentally: the triple photon states. I will comment on the new avenues these states open and present our recent results on triple-photon entanglement.
