从光子相关测量中获得的最著名的量是g（m）相关函数。在这里，我们介绍了一个新的程序来评估这些相关函数的基础上，高阶阶乘累积量CF，m，集成的相关函数的时间依赖性，即，总结在不同的时间跨度的可用信息。在一个系统的方式，高阶相关函数的信息内容，以及光子等待时间的分布被考虑在内。我们的方法大大提高了探测相关性的灵敏度，而且在实验中对有限的计数效率和时间分辨率是鲁棒的。它甚至可以应用于g（m）在短时间跨度内不可访问的情况。我们使用新的评估方案来分析耦合到单个量子点的等离子体激元腔的光子发射。我们得到的标准，必须持有，如果系统可以描述一个通用的Jaynes-Cummings模型。一个违反的标准可以解释的存在下，一个额外的激发量子点状态。二态模型
: Among the best known quantities obtainable from photon correlation measurements are the g ( m ) correlation functions. Here, we introduce a new procedure to evaluate these correlation functions based on higher-order factorial cumulants C F, m that integrate over the time dependence of the correlation functions, that is, summarize the available information at di ff erent time spans. In a systematic manner, the information content of higher-order correlation functions as well as the distribution of photon waiting times is taken into account. Our procedure greatly enhances the sensitivity for probing correlations and, moreover, is robust against a limited counting e ffi ciency and time resolution in experiment. It can be applied even in case g ( m ) is not accessible at short time spans. We use the new evaluation scheme to analyze the photon emission of a plasmonic cavity coupled to a single quantum dot. We derive criteria that must hold if the system can be described by a generic Jaynes − Cummings model. A violation of the criteria can be explained by the presence of an additional excited quantum dot state. two-state model
