Abstract (in Japanese) (See Japanese page) 
(in English) Two evaluation methods, the three-state method and the weak measurement method, were proposed for disturbances in quantum measurements, and some experimental verifications have been performed.
In this study, we propose an experimental method that has superiority in the number of measurements than any of them.
Our method directly and quantitatively acquires the disturbance as the decoherence of the auxiliary system.
A quantum circuit for that purpose was constructed, and the validity of the proposed method was verified by a concrete measurement model by simulation.
