中性原子量子处理器在规模和相干性方面已快速发展，但其实际性能仍受限于有限的量子电路迭代速率（qCIR）和信息吞吐量。本文实验演示了一种基于非破坏性读出和原子复用的高吞吐量中性原子系统，通过将片上光子接口与10量子比特阵列集成，实现了保留概率为99.7%的非破坏性读出，进一步得到原始qCIR为101Hz、后选择qCIR为74.8Hz。更重要的是，本文验证了一种通用的吞吐量优化方法，获得了归一化费舍尔信息速率为57.7Hz，与传统方法相比，可实现的吞吐量提升了一个数量级以上。研究结果为构建高吞吐量中性原子量子处理器确立了可行路径。
英文摘要
Neutral-atom quantum processors have rapidly advanced in scale and coherence, yet their practical performance remains constrained by limited quantum circuit iteration rates (qCIRs) and information throughput. Here we experimentally demonstrate a high-throughput neutral-atom system based on non-destructive readout and atom reuse. By integrating a chip-based photonic interface with a 10-qubit array, we implement non-destructive readout with a retention probability of 99.7%, and further achieve a raw qCIR of 101Hz and a post-selected qCIR of 74.8Hz. More importantly, we verify a general throughput optimization methodology and obtain a normalized Fisher information rate of 57.7Hz, improving the achievable throughput by more than one order of magnitude compared with conventional methods. Our results establish a practical route toward high-throughput neutral-atom quantum processors.
