Quantum sensing is a vast and emerging field enabling in-situ studies of quantum systems and
hence the development of quantum hybrid systems. This work creates the fundament of direct
superconducting-magnetic hybrid systems by developing a local microwave sensing scheme and
studying the influence of a static magnetic field on a superconducting qubit. Finally a
proof-of-principle hybrid system is demonstrated which opens the path towards
superconducting-magnetic quantum circuits.
