中文摘要：

为三个类型 Rydberg 原子的汗衫状态的产生的一个建议经由在一个分开的 Rydberg 状态和 EPR 对之间的相互作用被介绍。与以前的计划不同，我们不需要由使用微波灯联合地面状态，但是设置在激光之间的适当频率 detuning 和在地面状态和 Rydberg 层次之间的二原子转变消除二个地面状态退化，在实验更容易做现在的协议。而且，一系列数字模拟被做显示出可行性。

英文摘要：

A proposal for the generation of singlet states of three A-type Rydberg atoms is presented via the interaction between a separate Rydberg state and an EPR pair. Different from previous schemes, we do not need to couple ground states by using microwave lights but to set appropriate frequency detuning between lasers and two atomic transitions between ground states and Rydberg levels to eliminate the degenerate of the two ground states, making the present protocol more easily in experiment. Moreover, a series of numerical simulations are made to show the feasibility.
