| Research Abstract |
We studied a foundation of quantum mechanics and quantum information theory using the general probabilistic theories, which is considered to provide the most general framework of operationally valid probability theories. One of the goal of this study is to derive quantum mechanics based on purely physical principles, with the help of the recent development of the quantum information science. In particular, we have derived qubit system with appropriate physical principles and found general properties of correlations applicable to unconditionally secure key distribution.
