Description
Superconducting circuits (SCCs) are a favored platform for quantum computing. One potential source for decoherence in systems like the transmon is pair-breaking black body radiation. Currently no end-to-end simulation package exists to model the emission, and propagation of black body photons in experimental setups. Geant4, the state of the art particle physics simulation software, can only simulate free space propagation. Our work will build on Geant4 by adding the propagation of black body photons through volumes in experimental setups with one dimension comparable in size to the photon wavelength, where free space propagation is invalid. We use ANSYS HFSS for modeling such volumes. We present the current status of the code development and summarized plans for validation.
