偏振纠缠光子对的确定性腔QED源

A deterministic cavity-QED source of polarization entangled photon pairs

R. Garcia-Maraver, K. Eckert, R. Corbalan, J. Mompart

摘要:

我们提出了两个腔量子电动力学提案,它们具有相同的基本元素,允许通过三能级原子连续耦合到两个呈现偏振简并的单纵模高Q光学谐振器来确定性地产生纠缠光子对。在更快的方案中,三能级原子通过两个截断的拉比振荡产生偏振纠缠光子对,而在绝热方案中,考虑了一个违反直觉的受激拉曼绝热通过过程。虽然比前一个过程慢,但第二种方法在实验参数波动下非常有效和鲁棒,特别有趣的是,几乎对原子衰变完全不敏感。

英文摘要:

We present two cavity quantum electrodynamics proposals that, sharing the same basic elements, allow for the deterministic generation of entangled photons pairs by means of a three-level atom successively coupled to two single longitudinal mode high-Q optical resonators presenting polarization degeneracy. In the faster proposal, the three-level atom yields a polarization entangled photon pair via two truncated Rabi oscillations, whereas in the adiabatic proposal a counterintuitive Stimulated Raman Adiabatic Passage process is considered. Although slower than the former process, this second method is very efficient and robust under fluctuations of the experimental parameters and, particularly interesting, almost completely insensitive to atomic decay.
