| Research Abstract |
Among various features that distinguish the quantum world from the classical world, we have focused on “quantum coherence” and “quantum measurement,” and have explored their interesting interplay. We have worked at a variety of subjects, where quantum measurements play nontrivial roles, not simply capturing quantum coherence, but playing a crucial role for the emergence of quantum coherence, or providing us with unique ways of controlling quantum coherence. Through such research, we have approached the intriguing nature of the quantum-mechanical world and developed unique methodologies useful for quantum-information technologies.
