Outline of Final Research Achievements

This study which is based on Bohr's epistemological interpretation presents a new epistemological interpretation of physical quantity from information theoretical views. This interpretation means that physical quantities should be regarded as epistemological references to divide physical objects into our understanding parts. Furthermore, by applying this interpretation to weak value which is the outcome of weak measurement, weak value can be regarded as epistemological value which is depend on the epistemological reference, so-called quantum system. In other words, physical quantity and its value are depend on references which observers set, so they are available information through the references rather than physical properties.

Academic Significance and Societal Importance of the Research Achievements

本研究は、近年、論争となっている弱値の物理的解釈において、存在論的解釈が先行する中、認識論的な解釈を提示するという点において意義があるといえる。さらに、本研究の特徴ともいえる認識論的観点を物理学にもたらすアプローチは、ボーアの量子解釈を物理学全体に拡張するものであり「物理学とは何か」という伝統的な問いに対しても一石を投じる研究といえる。社会的意義の観点からすると、本研究は、いわゆる理系に属する物理学、人文系に属する哲学を結ぶ研究であり、国内の状況を鑑みて、哲学的分析の有用性を示すことができた考えている。
