We demonstrate the use of two high speed avalanche photodiodes in exploring higher order photon correlations. By employing the photon number resolving capability of the photodiodes the response to higher order photon coincidences can be measured. As an example we show experimentally the sensitivity to higher order correlations for three types of photon sources with distinct photon statistics. This higher order correlation technique could be used as a low cost and compact tool for quantifying the degree of correlation of photon sources employed in quantum information science.
我们展示了使用两个高速雪崩光电二极管来探索高阶光子相关性。通过利用光电二极管的光子数分辨能力，可以测量对高阶光子符合的响应。作为一个例子，我们通过实验展示了对具有不同光子统计特性的三种类型光子源的高阶相关性的灵敏度。这种高阶相关性技术可以用作一种低成本且紧凑的工具，用于量化量子信息科学中所使用光子源的相关程度。
