摘 要: 计算了混合迭加态的光场复振幅平方的实部算符和虚部算符的量子起伏,得到存在振幅平方压缩的两种混合迭加态,它们是迭加态中两Fock态的光子数之差为2和4的混合迭加态。 In this paper, the quantum fluctuation of the real component and complex component of the complex amplitude-squared of light field in mixed superposition states is calculated in detailed.Due to the result, we have obtained two kinds of mixed superposition states existing in amplitude-squared squeezing.They are mixed superposition states which involving two Fock states, the difference of photon number of this two Fock states is 2 or 4.Thus squeezing range of amplitude-squared is calculated.
