零光子减法(ZPS)是一种有条件的测量过程，它可以在不物理去除任何光子的情况下减少量子光学状态的平均光子数。这里我们展示了ZPS也可以用来将某些超泊松态转换成亚泊松态，反之亦然。结合著名的条件测量“不去”定理，这一效应导致了一套新的非经典标准，可以通过ZPS测量进行实验测试。
Zero-photon subtraction (ZPS) is a conditional measurement process that can reduce the mean photon number of quantum optical states without physically removing any photons. Here we show that ZPS can also be used to transform certain super-Poissonian states into sub-Poissonian states, and vice versa. Combined with a well-known"no-go"theorem on conditional measurements, this effect leads to a new set of non-classicality criteria that can be experimentally tested through ZPS measurements.
