Data and analysis code to support findings in "Superconducting qubit based on a single molecule: the nanotube gatemon" (2025). Use the Jupyter notebook Paper Figures.ipynb to inspect the data and reproduce the figures. The python packages microwave_analysis, gatemon_model, and qmpipeline were developed as part of the work and are also available on GitHub at https://github.com/qcmx. They are included here for archiving purposes and to simplify running the notebook.
