DOI Type Published on 10.21468/SciPostPhysCodeb.65 Article 2026-03-03 10.21468/SciPostPhysCodeb.65-r1.0 Codebase release 2026-03-03 Abstract Recent advances in machine learning (ML) have accelerated progress in calibrating and operating quantum dot (QD) devices. However, most ML approaches rely on access to large, representative datasets designed to capture the full spectrum of data quality encountered in practice, with both high- and low-quality data for training, benchmarking, and validation, with labels capturing key features of the device state. Collating such datasets experimentally is challenging due to limited data availability, slow measurement bandwidths, and the labor-intensive nature of labeling. QDFlow is an open-source physics simulator for multi-QD arrays that generates realistic synthetic data with ground-truth labels. QDFlow combines a self-consistent Thomas-Fermi solver, a dynamic capacitance model, and flexible noise modules to simulate charge stability diagrams and ray-based data that closely resemble experimental results. With an extensive set of parameters that can be varied and customizable noise models, QDFlow supports the creation of large, diverse datasets for ML development, benchmarking, and quantum device research. × TY - JOURPB - SciPost FoundationDO - 10.21468/SciPostPhysCodeb.65TI - QDFlow: A Python package for physics simulations of quantum dot devicesPY - 2026/03/03UR - https://scipost.org/SciPostPhysCodeb.65JF - SciPost Physics CodebasesJA - SciPost Phys.
