通过Jaynes-Cummings相互作用实现非关联原子的纠缠

Genuinely entangling uncorrelated atoms via Jaynes-Cummings interactions

Mazhar Ali

摘要:

我们研究了三对独立的Jaynes-Cummings系统,其中两个原子可能相互关联,但第三个原子与静止无关。我们调查的条件下,这些不相关的三个原子可能成为真正的纠缠。我们发现,如果与非关联原子相互作用的腔场与其他腔场具有经典关联,那么这个任务是不可能完成的。我们观察到,原子态可以成为真正的多体纠缠态,至少当原子不关联的腔与任何其他腔高度纠缠时。这是一个有趣的和不平凡的观察,并可能作为另一种技术,通过JC相互作用产生多体纠缠原子。研究结果可以实现与可用的实验装置。

英文摘要:

We study three independent pairs of Jaynes-Cummings systems such that two atoms might be correlated with each other but the third atom is uncorrelated with rest. We investigate the conditions under which these uncorrelated three atoms may become genuinely entangled. We find that this task is impossible if the cavity interacting with uncorrelated atom share classical correlations with any other cavity. We observe that atomic state can become genuine multipartite entangled, at least if the cavity with uncorrelated atom, is highly entangled with any other cavity. This is an interesting and non-trivial observation and may serve as another technique to generate multipartite entangled atoms via JC-interactions. The findings can be realized with available experimental setups.
