利用暗态机制实现交叉腔阵列中单光子的相干控制

Coherent control of single photons in the cross resonator arrays via the dark state mechanism

T. Tian, D. Z. Xu, T. Y. Zheng, C. P. Sun

摘要:

本文研究了两个耦合谐振腔阵列的简正模与一个?型原子局域化的交叉共振器。研究发现,由于Fano-Feshbach效应的基础上的暗态的?-型原子,光子在一个阵列中的转移可以很好地控制在另一个阵列中的光子的束缚态。这种概念性的结构可以在实际的腔QED系统中实现,从而实现单光子的量子开关。

英文摘要:

We study the single photon transfer in a hybrid system where the normal modes of two coupled resonator arrays interact with two transition arms of a ?-type atom localized in the intersectional resonator. It is found that, due to the Fano-Feshbach effect based on the dark state of the ?-type atom, the photon transfer in one array can be well controlled by the bound state of the photon in the other array. This conceptual setup could be implemented in some practical cavity QED system to realize a quantum switch for single photon.
