论文摘要
Rydberg Atom阵列构成了一个有希望的量子信息平台，在该平台中已经证明了数百个量子位的控制。进一步的扩展可能会从耦合到集成的光学或电子设备，允许量子网络和新的控制工具中显着受益，但是由于Rydberg对表面的电场噪声的敏感性，这种集成具有挑战性。我们证明，可以在纳米级介电设备的100微米距离内生成和维持Rydberg的相干性和两种原子纠缠。使用对单个力和纠缠辅助感应的连贯操纵，我们绘制了电场环境的时空特性，从而实现了其控制以及Rydberg阵列与微观和纳米级设备的整合。
Rydberg atom arrays constitute a promising quantum information platform, where control over several hundred qubits has been demonstrated. Further scaling could significantly benefit from coupling to integrated optical or electronic devices, enabling quantum networking and new control tools, but this integration is challenging due to Rydberg sensitivity to the electric field noise from surfaces. We demonstrate that Rydberg coherence and two-atom entanglement can be generated and maintained at distances of 100 microns from a nanoscale dielectric device. Using coherent manipulation of individual qubits and entanglement-assisted sensing, we map the spatio-temporal properties of the electric field environment, enabling its control and the integration of Rydberg arrays with micro- and nanoscale devices.
