Resetting qubits in a superconducting quantum processor

A quantum computing system comprising:

• a quantum processor cell comprising a plurality of qubit devices, the plurality of qubit devices comprising one or more tunable qubit devices;
• and
• a control system communicably coupled to the quantum processor cell and configured to perform operations comprising:
• identifying a tunable qubit device in the plurality of qubit devices that exhibits a frequency-dependent energy relaxation process in the quantum processor cell, wherein the frequency-dependent energy relaxation process is produced by a material defect in the quantum processor cell,
• identifying a first qubit frequency associated with a first relaxation time of the tunable qubit device,
• identifying a second qubit frequency associated with a second relaxation time of the tunable qubit device, wherein the second relaxation time is shorter than the first relaxation time due to the frequency-dependent energy relaxation process produced by the material defect,
• operating the tunable qubit device at the first qubit frequency while processing quantum information in the quantum processor cell,
• tuning the tunable qubit device from the first qubit frequency to the second qubit frequency, and
• resetting a qubit state of the tunable qubit device by the frequency-dependent energy relaxation process produced by the material defect.
