Mitigation-based benchmarking for NISQ devices

Abstract (in Japanese) (See Japanese page) 
(in English) This study applies quantum error mitigation (QEM) according to the type of quantum error and estimates the average gate error by quantitatively obtaining the errors of the evaluated gates only.
In particular, we use a measurement error evaluation circuit which is employed as a quantum circuit to get the error of the execution result and also to generalize the experimental setup for obtaining Ozawa’s measurement error.
This new method allows the error bounds to be obtained by considering the mitigation range of QEM. Here, the more quantitative discussion of the errors is possible than the conventional methods.
Furthermore, it can be easily extended to multiqubit systems and performed at a lower running cost.
