论文摘要
预示的单光子源是用于光学量子技术应用的最常用的来源。有强烈的需求，需要准确预测其光谱特征和时间相关性，而精度的提高。这与预示来源中的内在随机光子生成过程有关。在这里，我们介绍了由连续波泵泵泵泵增强的自发参数下降产生的信号式，信号信号和信号信号偶合的时间相关性的完整的理论描述。该理论很好地预测了测量值，该测量已在我们的设置中使用具有高时间分辨率的单个光子检测器进行了实验证实。这使我们能够详细解决和分析多光子相关功能。
Heralded single photon sources are the most commonly used sources for optical quantum technology applications. There is strong demand for accurate prediction of their spectral features and temporal correlations with ever increasing precision. This is particularly important in connection with the intrinsically stochastic photon-pair generation process in heralded sources. Here we present a complete theoretical description of the temporal correlation of a signal-idler, signal-signal and signal-signal-idler coincidences of photons generated by continuous wave pumped cavity-enhanced spontaneous parametric down-conversion. The theory excellently predicts the measurements, which has been experimentally confirmed in our setup utilizing single photon detectors with high temporal resolution. This enables us to resolve and analyze the multi-photon correlation functions in great detail.
