基于N-Λ型原子系统的1→N型分束器

1→N Beam Splitter of the N-Λ atomic Ensemble

分析N-Λ型原子系统的原子极化率,结果表明即使在全共振条件下,EIT效应并不一定产生,介质对信号场的色散和吸收关系与所有场的复拉比频率有关。信号场传播方程的解析分析表明,此系统可以把一束光分成不同频率的N束光,并且其强度和相位是可控的。暗态极化子分析表明它还可以用作1→N量子分束器,产生多体纠缠态。

The atomic susceptibilities of the N-Λ atomic ensemble show that the EIT effect not always occur even if the full atomic resonance.The analytical results of the propagation equations exhibit that one beam can be splitter into N beams with different frequencies,where the amplitude and phase can be controlled.Moreover 1→N quantum beam splitter is produced,which can generate some multipartite entangled states.
