Delft Charge Stability Diagram Dataset

  Delft Charge Stability Digram Dataset (D-CSD) contains 9850 quantum dot charge stability digrams measured on Si/SiGe and Ge/SiGe devices in the labs of Menno Veldhorst and Lieven Vandersypen at QuTech at Delft University of Technology. The charge stability diagrams are provided in raw .h5 format as well as .png image. The purpose of this dataset is to serve as a standard benchmark for machine learning and quantum data analysis community.   The CSDs directory contains the CSD dataset, with individual .h5 files for each CSD, storing voltage and measurement values. Plots of the CSDs, with the same name as the .h5 files, are stored in CSDs/_PNGs/.   The dataset was obtained using an ensemble classifier: a set of neural networks fine-tuned to classify CSD images as clean or noisy, based on a defined threshold.   All scripts used for labeling, training the ensemble classifier, and manipulating the data are located in the dataset_preparation directory. A detailed README is included, providing a step-by-step guide for reproducing the results.   Acknowledgements This research was sponsored in part by the Army Research Office (ARO) under Award No. W911NF-23-1-0110 and W911NF-17-1-0274.
