光计数统计是表征电磁场的重要工具，特别是对于具有不相关相位的场。在微波领域，连续测量而不是离散测量是常态。使用一种新的方法，我们恢复离散光子统计场正交测量的连续分布的累积量。累积量的使用允许感兴趣的信号和实验噪声之间的分离。使用参量放大器作为放大链的第一阶段，我们提取有用的数据从相干场的连续分布的六阶累积量，从而恢复到与远小于一个平均光子的信号相关的离散统计的三阶矩。
Photocount statistics are an important tool for the characterization of electromagnetic fields, especially for fields with an irrelevant phase. In the microwave domain, continuous rather than discrete measurements are the norm. Using a novel approach, we recover discrete photon statistics from the cumulants of a continuous distribution of field quadrature measurements. The use of cumulants allows the separation between the signal of interest and experimental noise. Using a parametric amplifier as the first stage of the amplification chain, we extract useful data from up to the sixth cumulant of the continuous distribution of a coherent field, hence recovering up to the third moment of the discrete statistics associated with a signal with much less than one average photon.
