论文摘要
我们考虑在遥远的谐振器中的光子状态的动力学，并在不同位置耦合到公共汽车谐振器。来自公共汽车谐振器的远处谐振器的频率同样失谐。这些频率的引导保持比每个谐振器与通用总线谐振器的耦合强度更大，以满足分散互动状态。在色散式中，我们表明系统的时间动力学在各个相互作用时间内都会在一个步骤中演变为任意W型状态。我们的结果表明，在超导谐振器系统中，可以通过高保真度实现一步的任意W型状态。
We consider the dynamics of the photon states in distant resonators coupled to a common bus resonator at different positions. The frequencies of distant resonators from a common bus resonator are equally detuned. These frequency detunings are kept larger than the coupling strengths of each resonator to the common bus resonator to satisfy the dispersive interaction regime. In the dispersive regime, we show that the time dynamics of the system evolve to an arbitrary W-type state in a single step at various interaction times. Our results show that a one-step generation of arbitrary W-type states can be achieved with high fidelity in a system of superconducting resonators.
