| 摘 要： | 提出了一种简单、可行的三原子W态制备方案，它是基于三个二能级原子与一个单模腔场共振相互作用实现的。通过控制原子与腔场相互作用时间和耦合参数，无需对腔场态的探测，就可获得三原子的W态。此外，讨论了在现有实验技术下本方案实现的可能性。

| Abstract: | We present a simple and realizable scheme to generate three-atom entangled W state, based on the resonant interaction of three two-level atoms with one single-mode cavity field. It is shown that such state can easily be achieved by controlling the interaction time of atom-cavity-field and the coupling constant without the detection of photon number within the cavity. In addition, the experimental feasibility within the realm of cavity QED is analyzed. |
