Abstract (in Japanese) (See Japanese page) 
(in English) The experimental demonstration of an adaptive quantum state estimation (AQSE) is reported. The strong consistency and asymptotic efficiency of AQSE have been mathematically proven. It has also been mathematically proven that the precision of AQSE outperforms the conventional state tomography. The angle of linear polarization of single photons is estimated using AQSE, and the strong consistency and asymptotic efficiency are experimentally verified.
