我们证明，通过使用具有内部增益的光电探测器对，我们能够量化“介观”强度范围（小于 100 个平均光子）中脉冲二分态的两个分量之间的光子数相关系数。我们将混合光电发射探测器的性能与多像素硅光子计数器的性能进行了比较，并证明，由于不存在显着噪声，因此可以评估光子数差异分布的方差，从而评估散粒噪声水平，而无需任何校正。
We demonstrate that by using pairs of photodetectors endowed with internal gain we are able to quantify the photon-number correlation coefficient between the two components of a pulsed bipartite state in the "mesoscopic" intensity regime (less than 100 mean photons). We compare the performances of hybrid photoemissive detectors to those of multipixel silicon photon counters and demonstrate that the absence of significant noise allows the evaluation of the variance of the distribution of the differences in photon numbers, and hence of the shot-noise level, without any correction.
