A Construction of Dynamical Entropy on CAR Algebras
Kyouhei Ohmura, Noboru Watanabe
The dynamical entropy on von Neumann algebras defined by Accardi, Ohya and Watanabe (AOW entropy) is a natural noncommutative extension of the classical dynamical entropy. On the o…

On Transmission Efficiency of Quantum Modulations
K. Ohmura, N. Watanabe
In quantum information theory, it is important to find modulations with low information loss for noisy channels. In this paper, using the quantum dynamical entropy and the quantum…

A Formulation of Rényi Entropy on -Algebras
Farrukh Mukhamedov, Kyouhei Ohmura, Noboru Watanabe
The entropy of probability distribution defined by Shannon has several extensions. Rényi entropy is one of the general extensions of Shannon entropy and is widely used in engineeri…
