摘要
为准备一个真正地纠缠的状态的一个洞量 electrodynamics 计划[一。Borras，等， J。Phys。一 40 (2007 ) 13407 ] 在六个二水平的原子上被建议。在计划，原子洞 detuning 比联合力量和必要准备时间的原子洞比 Rydberg 原子 lifespan 短得多的大得多。因此计划有二个不同特征，即，对洞腐烂和原子放射感觉迟钝。
A cavity quantum electrodynamics scheme for preparing a genuinely entangled state [A. Borras, et al., J. Phys. A 40 （2007） 13407] on six two-level atoms is proposed. In the scheme, the atom-cavity detuning is much bigger than the atom-cavity coupling strength and the necessary preparation time is much shorter than the Rydberg-atom lifespan. Hence the scheme has two distinct features, i.e., insensitive to the cavity decay and the atom radiation.
