在目前的工作中，我们推导出一种形式主义，可用于预测和解释的时间结构和可实现的双光子干涉（TPI）实验，使用光子从两个单独的来源。治疗特别是解决光子源于固态量子发射器，这往往是纯粹的失相和光谱扩散。因此，它包括相位和发射频率抖动的影响，除了不同的辐射寿命和相对的光谱失谐的影响。虽然治疗主要是针对后Hong-Ou-Mandel干涉实验，我们还提供了适用于任意线性光闸，依赖于TPI的广义方程。
In the present work, we derive a formalism that can be used to predict and interpret the time structure and achievable visibilities for two-photon interference (TPI) experiments using photons from two separate sources. The treatment particularly addresses photons stemming from solid state quantum emitters, which are often subject to pure dephasing and spectral diffusion. Therefore, it includes the impact of phase- and emission frequency-jitter besides the influence of differing radiative lifetimes and a relative spectral detuning. While the treatment is mainly aimed at interference experiments after Hong–Ou–Mandel, we additionally offer generalized equations that are applicable to arbitrary linear optical gates, which rely on TPI.
