摘　　要：随着量子比特规模的扩大,人工标定量子比特成本巨大且效率低下,因此量子测控的自动化工作势在必行。针对此问题,构建一个自动化量子测控的系统框架,包括测控实验、数据处理和决策判断等3个模块,以及测控实验库、数据处理函数库、测控经验库和测控数据库等4个数据库,并基于此完成单比特性质的自动化标定。对24个量子比特进行读取门和单比特门的标定,总共耗时2.7 h,平均每比特耗时6.75 min,效果上达到了平均单比特门保真度99.28%、读取保真度78.6%的水平。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 framework 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.
