In this project, we will study the parametric down-conversion in a cavity with integrated superconducting detectors under cryogenic conditions. By using ultrafast driving electronics, we will implement pump filtering in the time domain, by enabling the integrated detector only after the pump has decayed away. The herald photon remains resonant with the cavity, and can thus be detected. We will investigate the spectral properties of the correlated photons generated in this process, as well as optimise the nonlinear behaviour of parametric down-conversion under cryogenic conditions.

在本项目中，我们将研究低温条件下集成超导探测器腔中的参数下转换。通过使用超快驱动电子器件，我们将在时域实现泵浦滤波，只有在泵浦衰减后才启用集成检测器。先驱光子与腔保持共振，因此可以被探测到。我们将研究在此过程中产生的相关光子的光谱特性，以及在低温条件下优化参数下转换的非线性行为。
