We report the close form expressions of the photon number statistics for a generalized coherent state and a generalized photon-added coherent state, which are shown to be crucial for proposing a variety of quantum scissor operations. The analytically obtained distributions are also capable of predicting the precise laser intensity windows for realizing a variety of quantum scissors. Truncating a photon added state overcomes the selection rule of obtaining the lower order Fock states. Photon addition also enables us to obtain a higher order Fock state in a lower order superposition. The importance of circular geometry is also demonstrated for engineering such quantum scissors.
我们报告了广义相干态和广义加光子相干态的光子数统计的闭合形式表达式，这些表达式对于提出各种量子剪刀操作至关重要。通过分析得到的分布还能够预测实现各种量子剪刀的精确激光强度窗口。截断加光子态克服了获得低阶福克态的选择规则。加光子操作还使我们能够在低阶叠加中获得高阶福克态。还证明了圆形几何结构对于设计此类量子剪刀的重要性。
