Outline of Research at the Start

本研究では、情報と熱力学を融合させた理論、すなわち情報熱力学に基づいて、生体情報処理の理論的研究を行う。とくに、生体情報処理は本当に熱力学効率が高いのか、といった基本的な問いに答えることを目指す。また、情報理論の分野で注目を集めている「リソース理論」の考え方、さらにはトポロジーの概念を応用することで、狭義の情報熱力学にとどまらない多角的な理論研究を行う。さらに、情報幾何の手法と熱力学を組み合わせることにより、熱力学的な不確定性関係の新しい理論を発展させ、生体情報処理への応用を行う。

Outline of Final Research Achievements

The purpose of this project is not only to apply information thermodynamics to biological information processing, but also to extend the theory of information thermodynamics itself by introducing the perspectives of information geometry and topology. As a result, the following results have been obtained. First, by formulating the thermodynamic uncertainty relation in the short time limit, we established a method for estimating entropy generation that can be applied to real data in biological information processing. We also obtained various results on finite-time thermodynamics for stochastic processes and chemical reactions from the viewpoint of information geometry and optimal transport. For example, we revealed a fundamental relationship between the thermodynamic uncertainty relation and the Cramer-Rao bound. Furthermore, we found topological phenomena inherent to nonlinear systems and stochastic processes, and succeeded in constructing general theories of these phenomena.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果の学術的意義は、まず基礎物理の観点から情報熱力学の理論そのものを拡張し、新奇性の高い理論を構築したことである。情報幾何や最適輸送理論といった数理的な概念を取り入れることで、有限時間の熱力学についての新たな理論体系を構築した。さらにトポロジーについては、これまでほとんど研究されていなかった非線形系や確率過程にトポロジーの概念を拡張することに成功した。これらの成果は、生体情報処理におけるエントロピーの計測や、生体情報処理の頑健さの起源を明らかにするための基礎となるものである。また、アウトリーチや教科書の執筆を通して、研究分野の意義と展望について社会に広く発信することもできた。
