Dataset for Single‑Window Quantum Bandwidth Law for Open Quantum Dynamics

This dataset contains all numerical data and analysis code supporting the figures in the paper “Single‑Window Quantum Bandwidth Law for Open Quantum Dynamics” . The data are organised into two CSV folders (Main Text and Supplementary Information), corresponding to each figure panel. All results were generated using the open‑source Python package nonmarkovian‑bandwidth-law with two main scripts (QBL‑DPBV.py and QBL‑CPV.py). The dataset is provided under a CC BY 4.0 license, and all figures can be fully reproduced by running the scripts with the included CSV files and the parameter settings described in the paper.
