摘　　要：利用单模腔场与捕获原子团的相互作用,提出原子团之间最大纠缠态的制备方案.数值上给出原子团间的纠缠度随白噪声强度的变化关系.计算出系统的热纠缠及其存在的临界温度.A scheme to generate maximally entangled states of two trapped atomic groups via the interaction between the single-mode cavity field and the trapped atomic groups was proposed.The effects of atom decay on the entanglement preparation were presented and discussed.The thermal entanglement and its critical temperature were also presented.

关 键 词：纠缠态 原子团 热纠缠
