Design and Implementation of an Automated Measurement and Control System for Superconducting Quantum Chips

Abstract

As the scale of quantum bits expands,manual calibration of quantum bits becomes costly and inefficient.Therefore,the automation of quantum measurement and control is imperative.A frame-work for automated quantum measurement and control is constructed in this work,including 3 modules such as measurement and control experiment,data processing and decision judgment,and 4 databases such as measurement and control experiment library,data processing function library,measurement and control experience library and measurement and control database.The automated calibration of single-qubit properties is completed based on this framework.The calibration of readout gates and single-qubit gates for 24 quantum bits is accomplished in a total of 2.7 h,averaging 6.75 min per qubit.An average single-qubit gate fidelity of 99.28% and a readout fidelity of 78.6%is achieved.
