By integrating the tools of ultra-sensitive microwave bolometry with those of superconducting circuits (qubits), we have experimentally realised tunable photonic heat transport between mesoscopic thermal baths embedded in superconducting resonators, interfaced with a superconducting artifcial atom.

We will present recent observations of heat transport in two scenarios:

– where the resonators are symmetric, highlighting the role of the various coupling elements and the applicability of local vs global models for understanding this flux-tunable transport(1)

– where the resonators are asymmetric, yielding a rectification based on the direction of transport(2)
