Superconductors are a natural source of entangled electrons that can be used to induce nonlocal correlations through Cooper-pair breaking. In this work, the authors show that a Cooper-pair splitter utilizing quantum dots can be used as a photon bus to transfer energy between two distant resonators, by tuning gate voltages to match internal resonances. The proposed scheme has relevant applications in heat control and cooling at the nanoscale
