| Research Abstract |
Our topic is quantum statistical inference, which is statistical inference of quantum mechanical systems. We focused on statistical inference of correlated quantum systems and quantum channels, which are relatively new area. We successfully showed optimal measurements in variety of cases, and built some general theory. Also, we studied various properties of quantum correlation and quantum channels, and deepened the fundamental of quantum statistical inference.
