六原子纠缠态的制备(英文)

Preparation of Six-atoms entangled states

基于原子 -腔场相互作用 ,提出一个制备六原子纠缠态的方案。首先原子通过双光子跃迁 ,将腔制备成数态的迭加态 ,其次将制备在基态的六个全同二能级原子依次送入腔场 ,原子与腔场发生单光子共振相互作用。

A scheme for preparing six-atom entangled states is presented. It is based on atom-cavity-field interactions. Firstly, the cavity is prepared in the superposition of the number states through the atom undergoing a two-photon transition, the secondly, the six identical two-level atoms, which are all initially in their ground states, are sent through the cavity sequentially and can make resonant single-photon transition in the cavity. Then atomic entangled states are created and the cavity is left in the vacuum state.
