A recent theoretical analysis and experimental results show that interesting transport properties of a single microwave photon emerge when a quantum bit in a cavity is coupled to a one-dimensional waveguide. Here we adopt a real-space model Hamiltonian to give a unified approach which accounts for the experimental results, and make new predictions on the properties of single photon transport, such as the general Fano line shape, symmetric vacuum Rabi splitting for a leaky cavity at resonance, and a one-photon switching capability.
最近的理论分析和实验结果表明,当腔中的量子比特与一维波导耦合时,会出现单个微波光子有趣的输运特性。在此,我们采用实空间模型哈密顿量给出一种统一的方法来解释实验结果,并对单光子输运的特性做出新的预测,比如一般的法诺线形、共振时泄漏腔的对称真空拉比分裂以及单光子开关能力。
