模拟具有空间结构和外部调控的开放量子系统的动力学是量子信息科学中的重要挑战。经典数值求解器需联立求解主方程与场方程,计算开销大,难以用于大规模网络仿真或实时反馈控制。我们提出一种基于区域注意力的神经架构,学习结构化开放量子系统的时空演化。该模型引入物理定律的平移不变性作为归纳偏置,实现复杂度可扩展,并支持对时变全局控制参数的条件建模。在两类典型系统上验证:驱动耗散单量子比特和电磁诱导透明(EIT)量子存储器。模型在分布内与分布外控制协议下均保持高预测保真度,相比数值求解器提速达三个数量级。结果表明,该架构为具有空间结构的开放量子动力学建立了通用代理建模框架,对大规模量子网络仿真、量子中继与协议设计、实时实验优化及跨光-物质平台的可扩展器件建模具有直接应用价值。
原文摘要 · Abstract (English)
Simulating the dynamics of open quantum systems with spatial structure and external control is an important challenge in quantum information science. Classical numerical solvers for such systems require integrating coupled master and field equations, which is computationally demanding for simulation and optimization tasks and often precluding real-time use in network-scale simulations or feedback control. We introduce a regional attention-based neural architecture that learns the spatiotemporal dynamics of structured open quantum systems. The model incorporates translational invariance of physical laws as an inductive bias to achieve scalable complexity, and supports conditioning on time-dependent global control parameters. We demonstrate learning on two representative systems: a driven dissipative single qubit and an electromagnetically induced transparency (EIT) quantum memory. The model achieves high predictive fidelity under both in-distribution and out-of-distribution control protocols, and provides substantial acceleration up to three orders of magnitude over numerical solvers. These results demonstrate that the architecture establishes a general surrogate modeling framework for spatially structured open quantum dynamics, with immediate relevance to large-scale quantum network simulation, quantum repeater and protocol design, real-time experimental optimization, and scalable device modeling across diverse light-matter platforms.
