| Outline of Final Research Achievements |
It is one of central inssues in physics to clarify common properties among different phenomena. In particular, the concept of quantum/classical corrspondence appears in many research fields. Recent researches show that information-scientific concepts are quite powerful to attack this fundamental physics problem, and thus many reseachers are interested in this interdisciplinary field. In this three-year project, we clarify mathematical common structure inherent in many types of quantum/classical correspondences by means of singular value decompositon and information geometry. These mathematical methods decompose complicated quantum data into a set of simple informations with different length scales, and encode them into a classical curved space. Then, the analysis of geometric properties in the classical side is essential to understand the original quantum systems. In this sense, this project shows efficiency of these information-oriented approaches.
