摘要:

为量子处理器建立远程纠缠网络是量子信息科学中一项突出挑战。我们提出并分析了一种双原子物种架构,用于中性原子量子计算机的远程纠缠,该架构基于将光阱原子量子比特阵列与用于光子收集的快速光学系统集成。其中一种原子物种用于原子-光子纠缠,另一种物种提供本地处理。我们比较了两种光学方法可实现的远程纠缠生成速率:使用透镜的自由空间光子收集和近同心、长工作距离的谐振腔。腔内的激光冷却与俘获消除了从源区域机械输运原子的需要,从而允许快速重复速率。在优化腔精细度参数的情况下,预测在实验可行参数下远程纠缠生成速率可超过 $10^3~\ m s^{-1}$。

英文摘要:

Development of a network for remote entanglement of quantum processors is an outstanding challenge in quantum information science. We propose and analyze a two-species architecture for remote entanglement of neutral atom quantum computers based on integration of optically trapped atomic qubit arrays with fast optics for photon collection. One of the atomic species is used for atom-photon entanglement, and the other species provides local processing. We compare the achievable rates of remote entanglement generation for two optical approaches: free space photon collection with a lens and a near-concentric, long working distance resonant cavity. Laser cooling and trapping within the cavity removes the need for mechanical transport of atoms from a source region, which allows for a fast repetition rate. Using optimized values of the cavity finesse, remote entanglement generation rates $> 10^3~\rm s^{-1}$ are predicted for experimentally feasible parameters.
