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.

本项目将研究在锂离子波导上集成超导纳米线单光子探测器（SNSPD）的理论潜力和实验可行性，以实现测量引起的非线性。这种非线性产生于概率测量事件，因此可以在非常低的光水平下实现。通过集成这样的操作，我们可以利用干涉波导电路的固有相位稳定性和低损耗传输，并从理论上探索相位相关测量引起的非线性可以提供的操作范围。
