将半导体量子点和原子蒸气集成在一起的混合量子系统由于各部分的优势互补而成为可扩展量子网络的重要组成部分。量子点提供了近乎统一的不可分辨的按需单光子发射,包括前所未有的亮度-而原子蒸气系统提供了超精确的频率标准,并承诺为量子比特的存储提供长的相干时间。光谱滤波是量子点光子与原子成功连接的关键部件之一。在这里,我们提出了一种定制的法拉第反常色散滤光片,它基于铯-d1跃迁,用于将其与共振泵浦的量子点连接。提出的法拉第滤波器实现了窄带宽(Δω=2π×1 GHz)对两个Mollow三重态边带的同时滤波。这一结果为在光子量子网络中使用量子点作为单光子和级联光子的来源开辟了道路,这些光子与铯时钟跃迁的主频率标准一致。混合量子系统将高效的高质量量子点源与原子蒸气相结合,可以作为精确的频率标准或量子存储器。在这里,Portalupi等人。演示了一种优化的原子Cs-Faraday滤光器,该滤光器使用从半导体量子点发射的单光子。
Hybrid quantum systems integrating semiconductor quantum dots (QDs) and atomic vapours become important building blocks for scalable quantum networks due to the complementary strengths of individual parts. QDs provide on-demand single-photon emission with near-unity indistinguishability comprising unprecedented brightness—while atomic vapour systems provide ultra-precise frequency standards and promise long coherence times for the storage of qubits. Spectral filtering is one of the key components for the successful link between QD photons and atoms. Here we present a tailored Faraday anomalous dispersion optical filter based on the caesium-D1 transition for interfacing it with a resonantly pumped QD. The presented Faraday filter enables a narrow-bandwidth (Δω=2π × 1 GHz) simultaneous filtering of both Mollow triplet sidebands. This result opens the way to use QDs as sources of single as well as cascaded photons in photonic quantum networks aligned to the primary frequency standard of the caesium clock transition. Hybrid quantum systems combine efficient high-quality quantum dot sources with atomic vapours that can serve as precise frequency standards or quantum memories. Here, Portalupi et al. demonstrate an optimized atomic Cs-Faraday filter working with single photons emitted from a semiconductor quantum dot.
