This project will investigate the theoretical potential and experimental feasibility of integrating superconducting nanowire single-photon detectors (SNSPDs) on lithium niobate waveguides in order to implement a measurement-induced nonlinearity. Such nonlinearities arise from probabilistic mea-surement events and as such, can be implemented at very low light levels. By integrating such an operation, we can exploit the intrinsic phase stability and low-loss transmission of interferometric waveguide circuits and theoretically explore the range of operations that phase-dependent mea-surement-induced nonlinearities can offer.
