泄漏腔中双原子纠缠态的产生

Generation of entangled states of two atoms inside a leaky cavity

T. W. Chen, C. K. Law, P. T. Leung

摘要:

对泄漏腔中两原子的准确定纠缠进行了深入的理论研究。两个$Λ$型三能级原子,最初处于它们的基态,通过与单个光子的相互作用可以变得最大纠缠。通过计算出一个精确的解析解,我们表明,成功的概率主要取决于注入光子的光谱函数。利用腔光子,可以以一定的概率产生最大纠缠态,该概率总是小于50%。然而,对于具有较窄光谱宽度的注入光子,这种概率可以显著增加。特别是,我们发现的情况下,纠缠可以实现在一个单一的审判几乎单位的概率。

英文摘要:

An in-depth theoretical study is carried out to examine the quasi-deterministic entanglement of two atoms inside a leaky cavity. Two $Λ$-type three-level atoms, initially in their ground states, may become maximally entangled through the interaction with a single photon. By working out an exact analytic solution, we show that the probability of success depends crucially on the spectral function of the injected photon. With a cavity photon, one can generate a maximally entangled state with a certain probability that is always less than 50%. However, for an injected photon with a narrower spectral width, this probability can be significantly increased. In particular, we discover situations in which entanglement can be achieved in a single trial with an almost unit probability.
