Reveal the limitations of observation.
Welcome. I am Haruki Emori (江守陽規) — a 3rd-year Ph.D. student at the Graduate School of Information Science and Technology, Hokkaido University, a Junior Research Associate at RIKEN iTHEMS, and a Research Assistant at Teikyo University ACRO. I expect to graduate in March 2027.
What I work on
I work on the foundations of quantum mechanics, quantum measurement theory, and quantum information theory. I work on the foundations of quantum physics, quantum measurement theory, and quantum information theory. Observing natural phenomena, distilling the essence of physical laws, casting them into mathematics, and ultimately understanding and steering nature by repeating this cycle — a solid theory of measurement is indispensable for establishing these series of steps. My research therefore asks how far observation can reach: what the fundamental limits of measurement are, why such limits arise, and how to physically realize them that achieve the limits.
I am equally drawn to the fast-moving world of quantum technologies. I study the mathematical structures within quantum mechanics that make these technologies possible, and try to pin down the origin of the quantum behavior that lets quantum information processing outperform any classical counterpart.
More recently, I have worked at the borders where the mathematics of quantum mechanics meet other disciplines — cognitive, biological, and medical sciences — largely through experiments on real quantum computers and the design of quantum algorithms.
