摘要
提出一种利用一个二能级原子与一两模腔场的非共振相互作用制备纠缠压缩相干态的方案．当原子上、下能级的跃迁频率与腔场的每个模的频率都失谐较大时，原子的跃迁几率可以忽略．在此条件下，经适当制备的原子与初始时两模均处于各自的压缩相干态的腔场作用后，对原子进行选态测量即可使场态塌缩为纠缠压缩相干态．
A scheme is presented to generate the entangled squeezed coherent states via the nonresonant interaction of a two-level atom with a two-mode cavity field. When the detuning between the atomic transition frequency and the frequency of each mode is much large, the probability of atomic transition can be neglected. After the interaction of the appropriately prepared atom with the cavity field that are initially prepared in squeezed coherent states of each mode respectively, the entangled squeezed coherent states can be obtained by state-selective measurements on the atom.
