论文摘要
可以在室温下运行的高纯度单光子源(SP)对于无数应用程序(包括量子光子学和量子键分布)非常需要。在这项工作中,我们实现了基于与固体浸入式透镜(SIL)集成的六角硼(HBN)中原子缺陷(HBN)中的原子缺陷。 SIL将源效率提高了6倍,并且集成系统能够在室温下每秒产生超过一千万个单个光子。对于SPS在量子通信协议中的实际应用,我们的结果很有希望。
High-purity single photon sources (SPS) that can operate at room temperature are highly desirable for a myriad of applications, including quantum photonics and quantum key distribution. In this work, we realise an ultra-bright solid-state SPS based on an atomic defect in hexagonal boron nitride (hBN) integrated with a solid immersion lens (SIL). The SIL increases the source efficiency by a factor of six, and the integrated system is capable of producing over ten million single photons per second at room temperature. Our results are promising for practical applications of SPS in quantum communication protocols.
