摘要

抑制错误是在近期硬件上实现可靠量子计算的核心挑战之一。虽然错误纠正和缓解已经引起了很多关注,但我们认为量子电路结构本身是主动错误抑制的强大杠杆。在这项工作中,我们提出了一个统一的硬件自适应框架,用于噪声感知量子电路设计,其中电路拓扑和参数根据目标后端的噪声特征从底层开始协同优化。我们的框架支持广泛的量子任务-包括电路编译,量子态制备和一元近似-在一致的优化范例下。在五个IBM后端上进行的大量实验证实了我们方法的有效性,在真实噪声下,在所有任务中显示出显著的保真度增益。这些结果表明,通过结构感知设计的噪声抑制为提高NISQ硬件上的电路性能提供了一种强大而通用的策略。我们的框架将低级硬件约束与高级电路合成相结合,为在存在噪声的情况下实现更鲁棒和高效的量子编程铺平了道路。

Suppressing quantum errors by noise-aware circuit design
Suppressing errors is one of the central challenges in achieving reliable quantum computation on near-term hardware. While much attention has been paid to error correction and mitigation, we identify quantum circuit structure itself as a powerful lever for proactive error suppression. In this work, we present a unified and hardware-adaptive framework for noise-aware quantum circuit design, in which circuit topology and parameters are co-optimized from the ground up based on the noise profile of the target backend. Our framework supports a wide range of quantum tasks-including circuit compilation, quantum state preparation, and unitary approximation-under a consistent optimization paradigm. Extensive experiments on five IBM backends confirm the effectiveness of our method, showing significant fidelity gains across all tasks under realistic noise. These results demonstrate that noise suppression through structure-aware design offers a powerful and generalizable strategy for enhancing circuit performance on NISQ hardware. Our framework bridges low-level hardware constraints with high-level circuit synthesis, paving the way for more robust and efficient quantum programming in the presence of noise.
