We adapt the Quantum Monte Carlo method to the cascaded formalism of quantum optics, allowing us to simulate the emission of photons of known energy. Statistical processing of the photon clicks thus collected agrees with the theory of frequency-resolved photon correlations, extending the range of applications based on correlations of photons of prescribed energy, in particular those of a photon-counting character. We apply the technique to autocorrelations of photon streams from a two-level system under coherent and incoherent pumping, including the Mollow triplet regime where we demonstrate the direct manifestation of leapfrog processes in producing an increased rate of two-photon emission events.
我们将量子蒙特卡罗方法应用于量子光学的级联形式体系，从而能够模拟已知能量光子的发射。对如此收集到的光子计数进行统计处理，结果与频率分辨光子关联理论相符，拓展了基于特定能量光子关联的应用范围，特别是那些具有光子计数特性的应用。我们将该技术应用于在相干和非相干泵浦下两能级系统的光子流自相关，包括莫洛三重态区域，在该区域我们证明了蛙跳过程在产生双光子发射事件增加率方面的直接表现。
