摘要
提出一种利用经典场驱动单个二能级原子与一双模腔场相互作用制备腔场的纠缠相干态的方案。通过对原子的激光操纵 ,包括Stark效应和Rabi频率的交替控制 ,使原子与双模腔场相互作用后演化为纠缠态 ,再对原子进行选态测量即可获得所要制备的量子态。
A scheme is presented to generate the entangled coherent state of two-mode cavity-field with a driven atom.After the interaction of a two-level atom with a two-mode cavity field,the system of the atom and the acvity field envolves the entangled state by using laser manipulating the atom inducing Stark Effect and Rabi flip controls.The entangled coherent states can be obtained by state-selective measurement on the atom.
