Masanori Ohya (大矢 雅則, Ōya Masanori, born 1947) is a Japanese mathematician.

After he received a Ph.D. in Mathematical Physics and Information Science and Dr.Sc., he continuously worked on operator algebra, Quantum Entropy, quantum information theory and bio-information. He achieved results in the fields of Quantum Information and mathematical physics. In particular, he proposed his version of quantum mutual entropy. Note this quantity is not same as Holevo's chi quantity or coherent information( each of them plays important role in quantum information theory). The information theoretic meaning of Ohya's quantum mutual information is still obscure.

He also proposed 'Information Dynamics' and 'Adaptive Dynamics', which he applied to the study of Chaos theory, quantum information and biosciences as related fields.

Ohya studied multiple topics for more than thirty years, relating to quantum entropy, quantum information, chaos dynamics and life science. His main accomplishments are as follows:

They are explained in this book Watanabe 2007.
