摘要
本文构造了以奇偶q相干态为特例的一般叠加q相干态|α,θ〉q=c(|α〉q+eiθ|-α〉q),并研究了它的振幅M次方压缩性质,发现这种叠加态只存在振幅奇数次方压缩效应.并数值计算了叠加系数、变形参数对压缩的影响.
The superposition of q-coherent state|α,θ〉q =c (|α〉q+iθ|-α〉q), which contains even andodd q-coherent states as special cases,is constructed. Its amplitude Mth-power squeezing properties arestudied. The results show that this superposition states only appears amplitude odd-number-powersqueezing effect. The effects of the coefficient of superposition and deformed parameter on the degreeof squeezing are studied with the aid of numerical calculation.
