Abstract

Single photon sources are fundamental for applications in quantum computing, secure communication, and sensing, as they enable the generation of individual photons and ensure strict control over photon number statistics. However, current single photon sources can be limited by a lack of robustness, difficulty of integration into existing optical or electronic devices, and high cost. In this study, we present the use of off-the-shelf C₆₀ fullerene molecules embedded in polystyrene as room-temperature reliable single-photon emitters. As our results demonstrate, these molecules exhibit on-demand single-photon emission, with short fluorescence lifetimes and, consequently, high emission rates. The wide availability and ease of preparation and manipulation of fullerenes as single photon sources can pave the way for the development of practical, economic and scalable quantum photonic technologies.

C60富勒烯在室温下作为按需单光子源

单光子源是量子计算、安全通信和传感应用的基础，因为它们能够产生单个光子并确保对光子数统计的严格控制。然而，目前的单光子源可能受到缺乏鲁棒性、难以集成到现有光学或电子设备以及高成本的限制。在这项研究中，我们提出了使用现成的C60富勒烯分子嵌入聚苯乙烯作为室温可靠的单光子发射器。正如我们的研究结果所证明的那样，这些分子表现出按需单光子发射，荧光寿命短，因此发射率高。富勒烯作为单光子源的广泛可用性、制备和操作的便捷性为实用、经济和可扩展的量子光子技术的发展铺平了道路。
