AI 中文摘要
在可扩展量子计算中，在遥远量子比特间分发纠缠是关键要素。本文描述了一种可扩展量子互连，其产生远程纠缠的速率接近当前中性原子量子处理器两量子比特门兼容的水平。该方法利用原子里德伯态间的强偶极-偶极相互作用，在静止量子比特与传播光子间产生纠缠，无需光学腔。我们针对实际实验参数详细描述了所开发纠缠产生协议的最优条件，证明使用镱原子的里德伯态可实现大于3×10^5 s^-1的纠缠产生速率。鉴于该互连固有的可扩展性与设计灵活性，研究结果为基于中性原子量子架构的分布式网络提供了有前景的途径。
英文摘要
Distributing entanglement between distant qubits is a crucial element of scalable quantum computing. Here, we describe a scalable quantum interconnect that generates remote entanglement at rates approaching those compatible with two-qubit gates of current neutral-atom quantum processors. The proposed approach exploits the strong dipole-dipole interactions between atomic Rydberg states to generate entanglement between stationary qubits and propagating photons, without the need for an optical cavity. We provide a thorough description of the optimal conditions for the developed entanglement-generation protocol for realistic experimental parameters and demonstrate that entanglement-generation rates $\gtrsim 3\times 10^5$ s$^{-1}$ can be achieved using Rydberg states of ytterbium atoms. Given the inherent scalability and design flexibility of the proposed interconnect, our results suggest a promising approach towards distributed networks based on neutral-atom quantum architectures.
