Masanao Ozawa received his doctoral degree in science from Tokyo Institute of Technology in 1979, where he studied quantum information science and philosophy of science. His early studies established quantum measurement theory based on the notion of quantum instruments, and developed Gaisi Takeuti’s Boolean-valued analysis to settle Kaplansky’s conjecture in operator algebras using the forcing of cardinal collapsing in set theory. He developed quantum measurement theory to settle the controversy in the 1980s on sensitivity limit for gravitational wave detection, by refuting the quantum limit derived by Heisenberg’s uncertainty principle. This confirmed the supremacy of interferometers over resonators, and later led him to reformulate Heisenberg’s uncertainty principle with a correct error-disturbance relation. He has been serving as program committee members in international conferences and editorial board members for international journals in these research areas. He has held visiting positions at Harvard University, Northwestern University, and Pavia University. He is currently a Professor of Mathematics, Artificial Intelligence, and Data Science at Chubu University, and a Professor Emeritus at Nagoya University. He was awarded Mathematical Society of Japan Prize in 2008, Commendation for Science and Technology by the Ministry MEXT in 2010, International Quantum Communication Award in 2010, and Medal with Purple Ribbon by the Cabinet of Japan in 2015.
