On-Chip Photon-Mediated Magnon-Superconducting Qubit System and its Quantum Application

On-chip hybrid system utilizing photon-mediated coupling between magnon and superconducting qubit is proposed in this paper. By integrating a magnetic thin film in the z -axis with superconducting circuits, quantum operations between two-level magnon modes and qubit are enabled without increasing the circuit footprint, controlled by external magnetic field. Physical parameters of the coupled system are obtained using the proposed Multiphysics model following our design framework. Finally, we demonstrated the behavior of the system and performed quantum operations based on the Hamiltonian model.
