We propose and analyze an efficient scheme for realizing the high transfer rate for quantum router composed of two coupled-resonator waveguides (CRWs) channels coupled with N sequential cavities with embedded N four-level atoms. In this paper, we focus on the effect of the phase difference between different coupling constants which has been ignored in the previous works. In this scheme, we demonstrate that the phase difference between the coupling constants has a very large impact on the band spectra of single-photon propagating from one of the CRW into the other. Besides, as the number of atoms embedded in the two CRWs increases, the efficiency of a single photon being routed into other CRW can reach 100%. More importantly, we also find that if the phase difference of the coupling strength exists, even if there is atomic dissipation in the system, the transfer rate of a single photon not only it not decrease but it increases.

相位可调量子路由器

我们提出并分析了一种有效的方案，该方案可实现由两个耦合谐振器波导（CRW）通道与N个顺序腔和嵌入的N个四能级原子组成的量子路由器的高传输速率。在本文中，我们关注于不同耦合常数之间的相位差的影响，这在先前的工作中已被忽略。在该方案中，我们证明了耦合常数之间的相位差对从一个CRW传播到另一个CRW的单光子的能谱具有很大的影响。此外，随着嵌入在两个CRW中的原子数量的增加，单个光子路由到另一个CRW中的效率可以达到100％。更重要的是，我们还发现，即使存在耦合强度的相位差，即使系统中存在原子耗散，
