提出了一种光抽运方案，利用原子的自发辐射将与谐振子耦合的原子系统抽运到纠缠态。结果表明，光抽运可以使多体原子态渐近地到达任意稳定态，而与初始态无关。所提出的方案可以适用于各种物理系统。特别地，离子阱的实现完全在当前技术内。
We propose a scheme of optical pumping by which a system of atoms coupled to harmonic oscillators is driven to an entangled steady state through the atomic spontaneous emission. It is shown that the optical pumping can be tailored so that the many-body atomic state asymptotically reaches an arbitrary stabilizer state regardless of the initial state. The proposed scheme can be suited to various physical systems. In particular, the ion-trap realization is well within current technology.
