Abstract:It is an important step for quantum computing to outperform classical computing by evaluating quantum chips’ performance during their development to calibrate the degree of fit between the actual execution results and theoretical results of quantum algorithms. However, at present, there is no unified benchmark for evaluating the performance of quantum chips both in China and abroad, and the evaluation standards for local indicators of quantum chips can easily lead to misunderstandings about the overall performance of the chips. In view of this, this study first briefly describes performance indicators of existing quantum chips, then reviews current quantum chip evaluation methods by classifying evaluation technologies, and finally summarizes the existing problems of quantum chip evaluation technologies and looks forward to the future evaluation technology. In addition, the review can be easily sourced by those working in the relevant fields.
