Masanori Ohya


Masanori Ohya 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. 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.

Main research

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:
  1. Elucidation of Mathematical Bases of Quantum Channels,
  2. Formulation of Quantum Mutual Information,
  3. Information Dynamics,
  4. Analysis of Quantum Teleportation,
  5. Quantum Algorithm,
  6. Proposal of Adaptive Dynamics,
  7. Applications to the life sciences.
They are explained in this book.
