AI 中文摘要
我们引入一种验证流程，该流程利用可控多体弛豫来控制和校准量子硬件。在两台独立研发的中性原子处理器上，我们首次在开放系统中实现了多体量子姆佩姆巴效应。初始态工程构建了快、慢两条弛豫路径：快路径可在硬件噪声掩盖目标动力学前，获取原本难以实现的混合态物理；慢路径则放大了制备与操控过程中隐藏的缺陷。计算基测量直接且独立地对动力学可靠性进行基准测试，揭示了每台处理器作为多体模拟器的实际工作窗口，因此可通过其本应重现的动力学来评判处理器。互补响应可区分操控误差，推动自适应时间分辨方案，为硬件开发者提供可直接执行的修正措施，提升对目标动力学的忠实重现。这些结果确立了多体弛豫可作为可编程量子处理器通用的验证与校准工具。
英文摘要
We introduce a validation process that harnesses engineered many-body relaxation to control and calibrate quantum hardware. On two independently developed neutral-atom processors, we realize the many-body quantum Mpemba effect in an open system for the first time. Initial-state engineering creates fast and slow relaxation pathways: the fast pathway opens access to unreachable mixed-state physics before hardware noise obscures the target dynamics, whereas the slow pathway amplifies hidden imperfections in preparation and control. Computational-basis measurements directly and independently benchmark dynamical reliability, revealing each processor's actual operating window as a many-body simulator. The processors are thus judged by the very dynamics they are built to reproduce. Complementary responses disentangle control errors and drive an adaptive, time-resolved scheme that supplies hardware developers directly actionable corrections, enhancing faithful reproduction of the target dynamics. These results establish many-body relaxation as a transferable validation and calibration tool for programmable quantum processors.
