A Concise Method for Converting Operators into Anti-normal Sorting in Quantum Optics
This paper uses the coherent state representation to derive the basic operator identity for converting anti-normal sorting into normal sorting,and provides the basic method for converting general operators into anti-normal sorting.On this basis,the anti-normal product form of the compression opera-tor and its Wigner function are derived.
