摘要:

提出了一种耗散制备光腔中三原子W型纠缠态的方案。该方案是基于进入和离开目标状态的衰变过程之间的竞争。通过选择合适的系统参数,我们求解了整个演化过程,并利用有效算符理论设计了四个独立的衰变过程,使目标态成为量子系统的定态.该方案既不需要准备确定的初始状态,也不需要精确控制系统参数和准备时间。

英文摘要:

We propose a scheme for the dissipative preparation of W-type entangled steady-states of three atoms trapped in an optical cavity. The scheme is based on the competition between the decay processes into and out of the target state. By suitable choice of system parameters, we resolve the whole evolution process and employ the effective operator formalism to engineer four independent decay processes, so that the target state becomes the stationary state of the quantum system. The scheme requires neither the preparation of definite initial states nor the precise control of system parameters and preparation time.
