摘要
采用时间演化算符和数值计算方法,研究了两全同二能级纠缠原子与二项式光场相互作用过程中光场的量子特性.结果表明,光场的二阶相干性质和压缩效应与两原子体系纠缠度和二项式光场参数相关联,选择合适的系统参数,光场涨落可以被完全压缩.
In this article, the quantum properties of light field of the two identical two-level entangled atoms interacting with the binomial optical field were studied by means of time evolution operator and numerical calculations. The results show that the time evolution of the squeezing and coherence properties of the light field depends on the entanglement degree of the initial two identical two-level entangled atoms and the parameters of the binomial optical field. The optical field fluctuation can be completely squeezed via choosing appropriate parameters.
