论文摘要
杂种光子原子的综合电路，包括光子微腔和逃生场中的单个中性原子，具有量子信息处理的巨大潜力。在此平台中，原子提供了单光子的非线性和长寿记忆，它们与常规量子光子电路中出色的被动光子设备互补。在这项工作中，我们提出了一个稳定的平台，用于实现基于无用的光子芯片的混合光子原子电路。 By introducing high-order modes in the microring, a feasible evanescent-field trap potential well $\sim0.3\,\mathrm{mK}$ could be obtained by only $10\,\mathrm{mW}$-level power in the cavity, compared with $100\,\mathrm{mW}$-level power required in the scheme based on fundamental modes.基于我们的方案，具有相对较低激光功率的稳定的单原子捕获对于未来对高保真量子门，单光子源以及基于微腔中可控原子阵列的多体量子物理学的研究是可行的。
The hybrid photon-atom integrated circuits, which include photonic microcavities and trapped single neutral atom in their evanescent field, are of great potential for quantum information processing. In this platform, the atoms provide the single-photon nonlinearity and long-lived memory, which are complementary to the excellent passive photonics devices in conventional quantum photonic circuits. In this work, we propose a stable platform for realizing the hybrid photon-atom circuits based on an unsuspended photonic chip. By introducing high-order modes in the microring, a feasible evanescent-field trap potential well $\sim0.3\,\mathrm{mK}$ could be obtained by only $10\,\mathrm{mW}$-level power in the cavity, compared with $100\,\mathrm{mW}$-level power required in the scheme based on fundamental modes. Based on our scheme, stable single atom trapping with relatively low laser power is feasible for future studies on high-fidelity quantum gates, single-photon sources, as well as many-body quantum physics based on a controllable atom array in a microcavity.
