摘要

巨原子与波导之间的耦合在量子信息科学中具有重要意义。我们利用一个巨大的原子和两个波导来实现一个高效、安全、定向的寻址量子路由方案。通过调整相位，可以获得高效率的单光子传输速率。此外，我们还提出了一个基于超导电路的理论方案的潜在实现平台。通过仔细的数值选择和分析，证实了该平台的可行性。我们希望这项研究能够对未来量子网络的发展做出潜在的贡献。

Phase-modulated quantum routing with a giant atom

The coupling between giant atoms and waveguides is of great significance in quantum information science. We utilize a giant atom coupled with two waveguides to achieve a highly efficient, secure, and directional addressing quantum routing scheme. By adjusting the phases, single-photon transmission rates with high efficiencies can be obtained. Moreover, a potential implementing platform for our theoretical scheme is proposed based on the superconducting circuit. The feasibility of the proposed platform is confirmed by careful numerical selection and analysis. We hope that the research can potentially contribute to the development of future quantum networks.
