Microwave simulation of superconducting circuits is often done with conventional 3D full-wave analysis such as the finite element method (FEM). However, accurately representing large circuit structures using FEM is computationally expensive which can pose limits on the design complexity and number of qubits in simulations. In classical microwave simulation, coupled scattering parameter calculation (CSC) addresses this problem by decomposing the circuit structure into smaller individual blocks. In this talk, we bridge the gap between CSC methods and traditional quantum analysis to provide a modular and computationally efficient method for superconducting circuits simulation. Provided some assumptions on the circuit design, we successfully predict mode frequencies, loss rates and Hamiltonian parameters to the same degree of accuracy as previous methods with a reduced computational cost. This acceleration enables fast design parameter optimization using desktop-level computer hardware.
