摘要
提出了利用双光子J-C模制备三原子W纠缠态的方案。阐明了通过控制原子腔场的相互作用时间便能获得所制备的态。还指出利用这个模型制备W态比制备GHZ态更优越。此外,就腔QED技术对方案的实验实现作了分析。
A scheme is presented to produce an entangled three-atom W state by means of two-photon Jaynes-Cummings model. It is shown that such a state can easily be obtained by controlling the interaction time of atom-cavity-field. It is pointed out that this model is more advantageous in generating tripartite particle entangled W state than in GHZ state. In addition, an analysis of the experimental feasibility is presented within the realm of cavity QED.
