摘　　要：量子光源是量子信息科学技术的基石,对于推动光量子科技的进步至关重要。高效、稳定且易于获得的单光子源的实现是促进相关技术发展的关键。目前,六方氮化硼中的单光子源因其高亮度和优异的室温光学稳定性而备受关注。本文概述了六方氮化硼中单光子源的研究现状和物理特性,详细介绍了在六方氮化硼中实现精确定位单光子源的各种制备技术;并探讨了基于六方氮化硼的单光子源在不同应用领域的应用,如与光学微腔和波导的耦合以及通过外部电场或应力对它们的调制。最后,总结了六方氮化硼中单光子源所面临的机遇和挑战,并讨论了目前正在探索的研究方向以及未来的新可能性。Quantum emitter,the cornerstone of quantum information science and technology,is essential for ad-vancing light quantum science and technology.The realization of efficient,stable and easily accessible single photon sources is the key to promote the development of related technologies.Currently,single-photon sources in hexagonal boron nitride(h-BN)have attracted much attention due to their high brightness and excellent room-temperature opti-cal stability.This paper outlines the current research status and physical properties of single-photon sources in h-BN,details various preparation techniques for realizing precisely localized single-photon sources in h-BN,and ex-plores the application of single-photon sources based on h-BN in different applications,such as coupling with optical microcavities and waveguides,and their modulation by external electric fields or stresses.Finally,the paper summa-rizes the opportunities and challenges facing single photon sources in hexagonal boron nitride and discusses the re-search directions currently being explored as well as new possibilities for the future.
