摘要：
量子共振计算（QRC）已逐渐成为噪声中等尺度量子（NISQ）机器学习中的强大范式，通过利用量子态的高维动力学，使在最小训练开销下处理时序数据成为可能。本文介绍了QRC-Lab，一个开源、模块化的Python框架，旨在弥合理论量子动力学与应用机器学习工作流之间的差距。我们提供了QRC的严格定义，对比了物理方法和基于门的方法，并正式化了工具箱中使用的共振映射。QRC-Lab实例化了一个可配置的基于门的实验室，用于研究输入编码、共振连接性和测量策略，并通过三个教育案例研究验证这些概念：短期记忆重构、时序奇偶性（XOR）和NARMA10预测作为有意识的应力测试。此外，我们还包括一种受学习理论启发的泛化间隙扫描，以建立关于量子特征图容量控制的直觉。完整的源代码、实验脚本和可重复性资产已公开在：https://doi.org/10.5281/zenodo.18469026。
英文摘要：
Quantum Reservoir Computing (QRC) has emerged as a strong pa- radigm for Noisy Intermediate-Scale Quantum (NISQ) machine learning, ena- bling the processing of temporal data with minimal training overhead by exploi- ting the high-dimensional dynamics of quantum states. This paper introduces QRC-Lab, an open-source, modular Python framework designed to bridge the gap between theoretical quantum dynamics and applied machine learning work- flows. We provide a rigorous definition of QRC, contrast physical and gate- based approaches, and formalize the reservoir mapping used in the toolbox. QRC-Lab instantiates a configurable gate-based laboratory for studying in- put encoding, reservoir connectivity, and measurement strategies, and validates these concepts through three educational case studies: short-term memory re- construction, temporal parity (XOR), and NARMA10 forecasting as a deliberate stress test. In addition, we include a learning-theory motivated generalization- gap scan to build intuition about capacity control in quantum feature maps. The full source code, experiment scripts, and reproducibility assets are publicly available at: https://doi.org/10.5281/zenodo.18469026.
