主要研究双模奇、偶相干态(或双模Sch ro dinger猫态)的纠缠度与压缩函数的关系,其数值计算结果表明,双模奇、偶相干态的纠缠度与压缩函数均为相位φ的函数,并且当纠缠度周期性地增大时其压缩效应也逐渐减小.
Relations between entanglement and squeezing of two - mode even/odd coherent states (or cat) are studied by calculating the entanglement and squeezed function. Analytic expressions for the entanglement degree and squeezing function of two even/odd coherent states are the phasic function for 9. As the value of the entanglement degree in period increases, the squeezing effect become weaken.
