States with sub-Poissonian photon-number statistics obtained by post-selection from twin beams are experimentally generated. States with Fano factors down to 0.62 and mean photon numbers around 12 are reached. Their quasi-distributions of integrated intensities attaining negative values are reconstructed. An intensified CCD camera with a quantum detection efficiency exceeding 20% is utilized both for post-selection and beam characterization. Experimental results are compared with theory that provides the optimum experimental conditions.
通过对双光束进行后选择获得亚泊松光子数统计特性的状态在实验中得以产生。实现了Fano因子低至0.62且平均光子数约为12的状态。重建了积分强度的准分布，其值为负。使用量子探测效率超过20%的增强型电荷耦合器件相机进行后选择和光束表征。将实验结果与提供最佳实验条件的理论进行了比较。
