| 摘 要： | 提出了一种制备四原子Greenberger-Horne-Zeilinger 态的方案,它是基于原子-腔场相互作用,首先两个分离的腔初始时处于真空态,通过双光子转移把两个腔制备成缠结态。随后,与腔场发生共振相互作用的4 个等同的原子被分别送入两个腔,通过相互作用后,4 个原子处于GHZ态,而两个腔仍然处于真空态。

| Abstract: | A scheme for generating four-atom Greenberger-Horne-Zeilinger (GHZ) state is presented.It is based on atom-cavity-field interactions.Two separated cavities are both initially in the vacuum states,the entanglement of this two cavities is prepared by a two-photon transition (as cascade of two off-resonant dipole transitions).Subsequently,four identical two-level atoms,resonant with the cavities,are sent through the cavities,respectively.After interactions,the four atoms are in the GHZ states,while two cavities are left in the vacuum states. |
