Title: 手性量子光学

Abstract: At the most fundamental level, the interaction between light and matter is manifested by the emission and absorption of single photons by single quantum emitters. Controlling light--matter interaction is the basis for diverse applications ranging from light technology to quantum--information processing. Many of these applications are nowadays based on photonic nanostructures strongly benefitting from their scalability and integrability. The confinement of light in such nanostructures imposes an inherent link between the local polarization and propagation direction of light. This leads to {\em chiral light--matter interaction}, i.e., the emission and absorption of photons depend on the propagation direction and local polarization of light as well as the polarization of the emitter transition. The burgeoning research field of {\em chiral quantum optics} offers fundamentally new functionalities and applications both for single emitters and ensembles thereof. For instance, a chiral light--matter interface enables the realization of integrated non--reciprocal single--photon devices and deterministic spin--photon interfaces. Moreover, engineering directional photonic reservoirs opens new avenues for constructing complex quantum circuits and networks, which may be applied to simulate a new class of quantum many--body systems.

Abstract: 在最基本层面上，光与物质的相互作用通过单个量子发射器发射和吸收单光子来体现。 控制光与物质的相互作用是众多应用的基础，这些应用范围从光技术到量子信息处理。 如今，许多这些应用都基于光子纳米结构，这些结构因其可扩展性和集成性而受益匪浅。 在这种纳米结构中限制光会自然地使光的局部偏振和传播方向之间产生联系。 这导致了{\em 手性光与物质相互作用}，即光子的发射和吸收取决于光的传播方向、局部偏振以及发射器跃迁的偏振。 新兴的研究领域{\em 手性量子光学}为单个发射器及其集合提供了根本上新的功能和应用。 例如，手性光-物质界面能够实现集成的非互易单光子设备和确定性的自旋-光子接口。 此外，工程化定向光子库为构建复杂的量子电路和网络开辟了新途径，这些电路和网络可用于模拟一类新的量子多体系统。
