is a Japanese mathematician. After he revieved 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. ==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: #Elucidation of Mathematical Bases of Quantum Channels, #Formulation of Quantum Mutual Information (Entropy), #Information Dynamics, #Analysis of Quantum Teleportation, #Quantum Algorithm, #Proposal of Adaptive Dynamics, #Applications to the life sciences. # They are explained in this book . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Masanori Ohya」の詳細全文を読む スポンサード リンク
