论文摘要
固态量子点是有希望的候选物，用于将内部自旋自由度连接到发射光子状态的有效的轻度界面。但是，选择规则可以防止在此平台中结合有效的自旋控制和光学循环性。通过利用光子晶体波导，我们在这里实验可以通过光子状态工程进行实验证明高达$ \ of $ \ of 15 $的光循环，同时实现高富达自旋初始化和相干的光学自旋控制。这些功能为可扩展的多光子纠缠产生和芯片旋转式镜头大门铺平了道路。
Solid-state quantum dots are promising candidates for efficient light-matter interfaces connecting internal spin degrees of freedom to the states of emitted photons. However, selection rules prevent the combination of efficient spin control and optical cyclicity in this platform. By utilizing a photonic crystal waveguide we here experimentally demonstrate optical cyclicity up to $\approx15$ through photonic state engineering while achieving high fidelity spin initialization and coherent optical spin control. These capabilities pave the way towards scalable multi-photon entanglement generation and on-chip spin-photon gates.
