论文摘要
从供体到受体的远距离实现稳健的相干能量转移，在量子光学领域具有许多重要的应用。但是，很难使用常规方案实现。在这里，我们从理论上证明可以使用光子晶体平台来实现鲁棒的能量传递，其中包括拓扑保护的边缘状态和零维拓扑角腔。当分别将供体和受体分别放入一对分离的拓扑腔中时，可以在拓扑保护的界面状态下实现它们之间的能量转移。这种能量转移对各种缺陷都是可靠的，并且也可以在很长的距离内发生，这对生物检测，传感器，量子信息科学等非常有益。
The realization of robust coherent energy transfer with a long range from a donor to an acceptor has many important applications in the field of quantum optics. However, it is hard to be realized using conventional schemes. Here, we demonstrate theoretically that the robust energy transfer can be achieved using a photonic crystal platform, which includes the topologically protected edge state and zero-dimensional topological corner cavities. When the donor and the acceptor are put into a pair of separated topological cavities, respectively, the energy transfer between them can be fulfilled with the assistance of the topologically protected interface state. Such an energy transfer is robust against various kinds of defects, and can also occur over very long distances, which is very beneficial for biological detections, sensors, quantum information science and so on.
