Recent progress in quantum physics predicts a future revolution in the fields of communication, sensing, computing and simulation which rely on our hability to generate and control quantum states such as entanglement. Discovered more than thirty years ago, squeezed light has rapidly became an important tool for the implementation of quantum...

We demonstrate a squeezing experiment exploiting the association of integrated optics and telecom technology as key features for compact, stable, and practical continuous variable quantum optics. In our setup, squeezed light is generated by single pass spontaneous parametric down conversion on a lithium niobate photonic circuit and detected by...

We investigate the impact of photorefractive effect on lithium niobate integrated quantum pho-tonic circuits dedicated to continuous variable on-chip experiments. The circuit main building blocks, i.e. cavities, directional couplers, and periodically poled nonlinear waveguides are studied. This work demonstrates that, even when the effect of...
