摘要
提出了一个利用量子腔场与原子的共振相互作用制备多原子缠结态的方案 .首先将一个初态制备在基态和激发态的叠加态的二能级原子注入一个真空态腔场中 .原子通过腔时产生原子 -场缠结 .制备于基态的其它二能级原子分别以不同角度注入腔场 ,在与腔场相互作用时可制得多原子缠结态 ,而空腔仍然保持在真空态 .与现存的方案比较 。
A scheme for preparation of the many atom entangled state via the resonant interaction of quantized cavity with atom is presented.It is injected an two level atom initially prepared in the superposition of the ground state and excited state through the cavity prepared in the vacuum state.The atom passing through the cavity creates atom field entanglement.The other two level atoms prepared in the ground states are injected into the cavity at different angles,respectively.After the interaction with the cavity field,the many atom entangled state is produced and the cavity field is still in the vacuum state.Comparing with the existing schemes,ours is easier to realize experimently.
