AI 中文摘要
我们报告了一种固定阶克劳泽-霍恩-希米-霍尔特(CHSH)获取与报告协议,用于在Quandela公司商用、可通过云访问的Belenos处理器上的两个编码光子量子比特,由外部用户通过公共云接口端到端执行。每个逻辑量子比特是8模式单光子寄存器的7维零和扇区中的二维空间模式子空间,目标后选择线性光学受控-Z(理想成功概率1/9)在24个模式中的16个上耦合寄存器。主要量是接受的逻辑符合事件上的可操作CHSH得分S,每个完整的四设置过程作为实验单元。8个连续的同日过程均给出原始得分高于2;会话均值为2.40和2.58(样本标准差0.15和0.03),超额离散度Q/ν=6.1(ν=7)。计数合并的次要描述符为S_count=2.485±0.019,以及固定比率效率重加权模型场景S^rw_count=2.380±0.021,其最弱的重加权过程(2.040±0.062)在1σ内与2重叠。该重加权是存档元数据模型场景,而非校正后的平台得分;临时κ∈[1.2,1.8]应力扫描(非校准不确定度带)跨度为2.341-2.441。设置顺序固定,编译后的映射未返回,且残留远程设置边缘仍存在,因此数据支持可操作参考获取,而非纠缠见证或跨平台基准测试主张。奇偶校验术语标记编码子空间;未执行症候测量。计数记录、作业标识符、电路构建代码和分析已公开存档,并带有提交目标的内容哈希。
英文摘要
We report a fixed-order Clauser-Horne-Shimony-Holt (CHSH) acquisition and reporting protocol for two encoded photonic qubits on Quandela's commercial, cloud-accessible Belenos processor, executed end-to-end by external users through the public cloud interface. Each logical qubit is a two-dimensional spatial-mode subspace in the seven-dimensional zero-sum sector of an eight-mode single-photon register, and a target postselected linear-optical controlled-$Z$ (ideal success probability $1/9$) couples the registers on $16$ of $24$ modes. The primary quantity is the operational CHSH score $S$ on accepted logical coincidences, with each complete four-setting pass as the experimental unit. Eight sequential same-day passes each gave a raw score above $2$; session means were $2.40$ and $2.58$ (sample standard deviations $0.15$ and $0.03$), with excess dispersion $Q/ν=6.1$ ($ν=7$). Count-pooled secondary descriptors are $S_{\mathrm{count}}=2.485\pm0.019$ and a fixed-ratio efficiency-reweighted model scenario $S^{\mathrm{rw}}_{\mathrm{count}}=2.380\pm0.021$, whose weakest reweighted pass ($2.040\pm0.062$) overlapped $2$ within $1σ$. The reweighting is an archived-metadata model scenario, not a corrected platform score; an ad hoc $κ\in[1.2,1.8]$ stress scan (not a calibrated uncertainty band) spans $2.341$-$2.441$. Setting order was fixed, the compiled mapping was not returned, and residual remote-setting marginals remain, so the data support an operational reference acquisition rather than an entanglement-witness or cross-platform benchmarking claim. The parity-check terminology labels the encoding subspace; no syndrome measurement was performed. Count records, job identifiers, circuit-construction code, and analysis are openly archived with content hashes for the submitted targets.
