检测不允许对光电计数事件进行经典解释的非经典特性是量子光学的关键主题之一。然而，迄今为止，对单模场的各个非经典效应的观察实际上仅限于亚泊松统计和正交压缩。我们证明，添加光子的经典（相干或热）态在所有阶的创造和湮灭算子中表现出广义的非经典特征，从而成为研究高阶非经典效应的有希望的候选者。我们的分析证明了这些效应在非理想实验条件下的稳健性。
Detecting nonclassical properties that do not allow classical interpretation of photoelectric counting events is one of the crucial themes in quantum optics. Observation of individual nonclassical effects for a single-mode field, however, has been so far practically confined to sub-Poissonian statistics and quadrature squeezing. We show that a photon-added classical (coherent or thermal) state exhibits generalized nonclassical features in all orders of creation and annihilation operators, thereby becoming a promising candidate for studying higher-order nonclassical effects. Our analysis demonstrates the robustness of these effects against nonideal experimental conditions.
