标题： Discrete photon statistics from continuous microwave measurements

摘要： 光电计数统计是表征电磁场的重要工具，特别是在相位无关的场中。 在微波领域，连续测量而非离散测量是常态。 通过一种新方法，我们从场正交测量的连续分布的累积量中恢复出离散光子统计。 使用累积量可以将感兴趣的信号与实验噪声分离。 使用参数放大器作为放大链的第一级，我们从相干场的连续分布的六阶累积量中提取有用数据，从而恢复出与平均光子数远小于一的信号相关的离散统计的三阶矩。 显示英文摘要

摘要： 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.
