Abstract: A method comprises causing a plurality of qubit calibration procedures to be performed on one or more qubits in accordance with an automatic qubit calibration process. Log data is stored comprising at least: a record identifying one or more calibration procedures that have been performed, and information relating to the result of the respective calibration procedures. Training data is selected from the log data and is received at a learning module operating at one or more computing devices. A supervised learning model is trained at the learning module to select qubit parameters to be calibrated and/or checked.

Abstract: A quantum computing device includes: a qubit; a single XYZ control line, in which the qubit and the single control line are configured and arranged such that, during operation of the quantum computing device, the single XYZ control line allows coupling of an XY qubit control flux bias, from the single XYZ control line to the qubit, over a first frequency range at a first predetermined effective coupling strength, and coupling of a Z qubit control flux bias, from the single XYZ control line to the qubit, over a second frequency range at a second predetermined effective coupling strength.
