论文摘要
来自固态量子发射器的单个光子在光子量子技术的发展中起着至关重要的作用。高阶状态，例如n-photon fock状态，允许应用程序，例如在量子增强的传感中。在这项研究中，我们利用在D1线上的热剖腹蒸气的分散，由于缓慢的光线效应而实现一个和两光子群的时间延迟。单光子是从INGAAS量子点按需生成的，而它们在梁分离器处的量子干扰用于生成两光子的Fockstate。我们验证了一个和两光子群的成功传播和时间延迟，而同时延迟（5倍初始光子长度）同时获得了高传输（〜90％）。
Single photons from solid-state quantum emitters are playing a crucial role in the development of photonic quantum technologies. Higher order states, such as N-photon Fock-states allow for applications e.g. in quantum-enhanced sensing. In this study, we utilize the dispersion of a hot cesium vapor at the D1 lines to realize a temporal delay for one and two-photon Fock-states as a result of the slow-light effect. Single photons are generated on-demand from an InGaAs quantum dot, while their quantum interference at a beam splitter is used to generate a two-photon Fockstate. We verify the successful propagation and temporal delay of both the one and two-photon Fock-states, while a significant delay (5x initial photon length) with simultaneous high transmission (~90 %) is achieved.
