Claim 13:
14. A quantum computing system comprising:
a quantum processor cell comprising qubit devices; and
a control system in communication with the quantum processor cell, the control system configured to perform operations comprising:
performing, by executing a calibration subroutine, a calibration process in the quantum computing system to identify a value of an operating parameter of the quantum computing system, wherein the calibration process comprises:
performing measurements on a quantum computing device in the quantum computing system; and
interpreting the measurements to extract a control parameter and a device characteristic for the quantum computing device;

determining, by executing a stability analysis subroutine, a stability of the operating parameter by analyzing a variation of the value in response to a change in a condition of the quantum computing system;
updating a stability model of the quantum computing system based on the stability of the operating parameter, wherein the stability model comprises a statistical model representing the value of the operating parameter as a function of time and configured to predict future values of the operating parameter;
scheduling, by executing a runtime scheduler, a recalibration of the operating parameter based on the future values of the operating parameter predicted by the stability model; and
executing a quantum algorithm in the quantum computing system based on the value of the operating parameter identified by the calibration process.
