Development of quantum operation devices using single-photon-level nonlinear interaction between photons and solids

我们提出了利用光子和固态量子系统之间的单光子级非线性相互作用的量子操作装置。为了实现这些器件的物理实现，我们研究了(1)基于光纤的扫描微腔系统的发展，(2)单个金刚石NV中心和单个半导体量子点的光学响应。(3)利用光子与aΛ-level系统之间的耦合系统进行了量子操作器件的理论研究。

We propose quantum operation devices utilizing single-photon-level nonlinear interaction between photons and solid-state quantum systems. Toward the physical implementation of such devices, we have investigated (1) the development of a fiber-based scanning microcavity system, and (2) the optical responses of a single diamond NV center and a single semiconductor quantum dot. We also carried out (3) the theoretical study on the quantum operation devices utilizing coupled systems between photons and aΛ-level system.
