我们实验研究了一种直接表征非经典光束的光子数分布的方法，该方法只使用标准的二元探测器，可以容忍损失。这是通过使用有关源的少量先验信息校准检测器在一次测量中实现的。我们演示了通过条件检测由参数下转换产生的双模压缩态来创建自由传播的预示双光子数态的技术。
We experimentally investigate a method of directly characterizing the photon-number distribution of nonclassical light beams that is tolerant to losses and makes use of only standard binary detectors. This is achieved in a single measurement by calibrating the detector using some small amount of prior information about the source. We demonstrate the technique on a freely propagating heralded two-photon-number state created by conditional detection of a two-mode squeezed state generated by parametric down-conversion.
