我们提出了一种类似零差的检测方案，涉及光子数分辨探测器来区分受均匀相位噪声或高斯相位噪声影响的两个相干态。使用两个混合光电探测器进行原理验证实验，其输出用于后处理以计算逐个镜头的光子数差异。该策略的性能根据区分噪声相干信号的误差概率来量化，该误差概率是特征噪声参数的函数。
We propose a homodyne-like detection scheme involving photon-number-resolving detectors to discriminate between two coherent states affected by either uniform or gaussian phase noise. A proof-of-principle experiment is performed employing two hybrid photodetectors, whose outputs are used in post processing to calculate the shot-by-shot photon-number differences. The performance of the strategy is quantified in terms of the error probability in discriminating the noisy coherent signals as a function of the characteristic noise parameters.
