Guided-wave solutions for non-classical state production

We demonstrate the possibility of generating non-Gaussian states of light by exploiting a setup fully based on plug-and-play guided-wave components from classical telecom and non-linear optical technologies. Our scheme relies on heralded single photon subtraction from single mode squeezed states generated in a single-pass configuration in nonlinear optical waveguides and allows generating Schrodinger kitten quantum optical states. We discuss the different parameters affecting the shape of obtained states by comparing the theory and the numerical simulations.
