摘要
我们研究了量子光学理论中的宇称算符及其应用。我们用有序算符内的积分方法,从宇称变换的物理意义出发自然地导出量子宇称算符的明确表达式;并将宇称变换和其它量子变换(如坐标-动量互变、压缩变换等)结合在一起考虑,构建了联合变换算符。最后给出了宇称算符在构建共轭纠缠态表象的应用。
With the application of the method of integration within ordered product of operators,we derive the parity operator of quantum optics stemming from its physical meaning.We also combine the parity transform with other quantum mechanical transforms (coordinate-momentum mutual transform,squeezing) to make up combinatorial transforms.The application of parity operator in constructing the conjugate bipartite entangled state is also presented.
