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
摘要
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。
Abstract
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.
