Research showcase: published devices and results, reproduced

Notebooks that reproduce a published device or result. Each is listed once here; the table at the end gives the source, what is reproduced, and what it needs.

Featured: package modes and qubit couplings

Six notebooks follow R. Molavi et al., arXiv:2609.22442: the couplings of a 10 × 10 transmon array to the modes of its metal package. They go from an analytic estimate (4.41) to a full-wave model of the whole package (4.45); 4.46 then looks inside that model term by term. They use gmsh and a scikit-fem Maxwell solver in place of HFSS (pip install "quantum-metal[skfem]").
