Using a sub-Poissonian optical field generated from a weak twin beam by photon-number resolving post-selection we have simultaneously observed higher-order non-classicalities in photocount moments (sub-Poissonian statistics) and probabilities (witnessed by the Klyshko inequalities). Up to the seventh-order non-classicalities in photocount moments simultaneously with up to the eleventh-order non-classicalities in photocount probabilities have been experimentally observed. Non-classicality counting parameters of different orders as experimental counterparts of the theoretical Lee non-classicality depth have been suggested to quantify and also mutually compare the robustness of these non-classicalities against the noise.
通过光子数分辨后选择从弱双光束产生亚泊松光场，我们同时在光计数矩（亚泊松统计）和概率（由克利什科不等式见证）中观测到了高阶非经典性。实验观测到了光计数矩中高达七阶的非经典性，同时光计数概率中高达十一阶的非经典性。已提出不同阶的非经典性计数参数作为理论李非经典性深度的实验对应物，以量化并相互比较这些非经典性对噪声的鲁棒性。
