Abstract We present a transmon qubit fabrication technique that yields systematic improvements in T 1 relaxation times. We encapsulate the surface of niobium and prevent the formation of its lossy surface oxide. By maintaining the same superconductin

We report achievement of non-Cu-matrix critical current density (Jc) in internally-oxidized Nb3Sn superconductors that surpasses the best state-of-the-art Nb3Sn and the Jc specification of the Future Circular Collider. We then explore the mechanism o
