我们报道了在单光子发射体(SPE)上用光子相关测量观测到强度自相关函数中的反常反聚束下降。我们发现，观测到的反常凹陷是SPE量子性质的一种表现。正确考虑了量子二能级系统中的布居动力学，重新定义了强度自相关函数。这对于精确评估SPE中多光子产生的最低能级概率，从而实现用于量子信息和通信的多功能纯SPE具有重要意义。(C)2012年美国物理研究所。[http://dx.doi.org/10.1063/1.4760222]
We report the observation of an anomalous antibunching dip in intensity autocorrelation function with photon correlation measurements on a single-photon emitter (SPE). We show that the anomalous dip observed is a manifestation of quantum nature of SPEs. Taking population dynamics in a quantum two-level system into account correctly, we redefine intensity autocorrelation function. This is of primary importance for precisely evaluating the lowest-level probability of multiphoton generation in SPEs toward realizing versatile pure SPEs for quantum information and communication.
