超高质量因子光子晶体纳米腔由于能将光限制在一个超小的区域内，并能实现光与物质之间的强相互作用而备受关注。利用空腔量子电动力学方法实现量子信息处理的一个重要步骤是在这些空腔之间传输光子的鲁棒方法。我们提出并从理论上研究了一种在强耦合、远距离光子晶体纳米腔间通过空腔特性在时域绝热变化来传递光子的方案。添加一个中间纳米腔用于控制，允许在客观纳米腔之间有效地进行光传递。由于该方案采用绝热传递，因此对控制参数和控制时间都具有鲁棒性。
Ultra-high-quality factor photonic crystal nanocavities are attracting much attention because they can confine light into an ultra-small region and enable strong interaction between light and matter. One important step toward the realization of quantum information processing with cavity quantum electrodynamics approaches is a robust method that transfers photons among such cavities. We propose and theoretically investigate a scheme to transfer photons between strongly coupled, distant photonic crystal nanocavities by an adiabatic change in the cavity characteristics in the time domain. Adding one intermediate nanocavity for control allows efficient light transfer between objective nanocavities. Because our scheme utilizes adiabatic transfer, its operation is robust for both the control parameters and the control timing.
