Quasiparticles in Superconducting Qubits with Asymmetric Junctions
Designing the spatial profile of the superconducting gap—gap engineering—has long been recognized as an effective way of controlling quasiparticles in superconducting devices. In aluminum films, their thickness modulates the gap; therefore, standard fabrication of Al/AlO_{x}/Al Josephson junctions,...
