Abstract
A system for adjusting qubit frequency includes a qubit device having a Josephson junction and a shunt capacitor coupled to electrodes of the Josephson junction. A cantilevered conductor is separated from the shunt capacitor by a spacing. An adjustment mechanism is configured to deflect the cantilevered conductor to tune a qubit frequency for the qubit device.
