SQuADDS_DB - a Superconducting Qubit And Device Design and Simulation Database

The SQuADDS (Superconducting Qubit And Device Design and Simulation) Database Project is an open-source resource aimed at advancing research in superconducting quantum device designs. It provides a robust workflow for generating and simulating superconducting quantum device designs, facilitating the accurate prediction of Hamiltonian parameters across a wide range of design geometries.

Generalized Interdigital Capacitor Sweep

coupler-GeneralizedCapNInterdigital-cap_matrix contains 20,062 Q3D capacitance-matrix simulations for GeneralizedCapNInterdigital, contributed by Saikat Das of the Levenson-Falk Lab at USC. The canonical terminal names are north and south; legacy top and bottom fields are retained as compatibility aliases.

The imported q3d_cap campaign stores its converged Maxwell matrix in CSV as pF. SQuADDS converts the final adaptive pass to fF (multiply by 1,000), retains the physical negative off-diagonal Maxwell entries, and exposes positive pairwise magnitudes such as north_to_south in the public result fields. This matches the unit and sign conventions used by the rest of SQuADDS_DB.
