Abstract
Systems and techniques that facilitate trimmable inductors for qubit frequency tuning are provided. In various embodiments, a device can comprise a Josephson junction. In various aspects, the Josephson junction can be shunted by a capacitor, and a trimmable inductor can couple the Josephson junction to a pad of the capacitor. In various cases, the trimmable inductor can comprise a first conductive path that includes a severable and/or weldable superconducting bridge and a second conductive path that is in parallel with the first conductive path. In various aspects, severing and/or welding the severable and/or weldable superconducting bridge can controllably change an inductance of the trimmable inductor, which can commensurately change a resonant frequency of a qubit formed by the Josephson junction and the capacitor.
