摘要
证明了量子光学中一个十分有用的指数算符恒等式,并应用这一恒等式求出了粒子数表象中光场的单模压缩真空态和双模压缩真空态的态函数.
A very useful identical equation of an exponential operator in quantumoptics has been proved.An4 by means of this equation, the state functions of a single-mode squeezed vaccum state and a bimodal squeezed vacuum state have been obtained in the number state representation.
