Bring up and calibration software solution developed at Chalmers University

We showcase a new bring-up, calibration and characterization software solution that is used to evaluate the performances of our multi-qubit processors. The software consists of two layers; a library of experiments for one and two-qubit operations, which is based on the publicly available Tergite-autocalibration [1] and a new orchestration layer that performs chip-wide operations. This software solution is compatible with the Tergite framework [2], which was developed by the group to operate quantum processors.

We demonstrate the capabilities of the software including calibration of single-qubit gates to median value above 99.8%, measure crosstalk between qubits and suggestions of possible mitigation strategies. We also showcase an effective procedure for calibrating two qubit gates in a 25-qubit device in less than a day, with daily calibrations taking about 2 hours. Finally, we present the monitoring capabilities of our solution by showing characterization performances over time.
