论文摘要
按需和有效的光子存储是量子信息处理和长距离量子通信的重要元素。大多数量子存储协议都需要批量系统才能存储光子。但是，随着用于量子信息处理的集成光子芯片平台的出现，芯片量子记忆受到了极大的追捧。在本文中，我们仅使用单原子腔设置为多模式光子量子存储器提出了一个协议。我们表明，一个包含频率梳子耦合到光腔的单个原子可以有效地存储光子。此外，该方案也可以用于存储光线极化状态。作为示例，我们表明，与纳米量波导腔耦合的rubium和剖宫产原子可以成为实现我们计划的有前途的候选人。这提供了可以在集成光子芯片中使用的稳健有效的芯片量子记忆。
On-demand and efficient storage of photons is an essential element in quantum information processing and long-distance quantum communication. Most of the quantum memory protocols require bulk systems in order to store photons. However, with the advent of integrated photonic chip platforms for quantum information processing, on-chip quantum memories are highly sought after. In this paper, we propose a protocol for multi-mode photonic quantum memory using only single-atom-cavity setup. We show that a single atom containing a frequency comb coupled to an optical cavity can store photons efficiently. Further, this scheme can also be used to store polarization states of light. As examples, we show that the Rubidium and Cesium atoms coupled to nanophotonic waveguide cavities can serve as promising candidates to realize our scheme. This provides a possibility of a robust and efficient on-chip quantum memory to be used in integrated photonic chips.
