Quantum Walk Lab (Etsuo Segawa)
Machine-translated · View original
The lab studies quantum walks on graphs from a mathematical perspective.
AboutAbout the lab
Studying quantum walks on graphs mathematically.
Professor Etsuo Segawa's research fields are quantum walks and discrete mathematical models.
The university's researcher directory lists papers on quantum walks on graphs and on models that bridge random walks and quantum walks.
The professor has also contributed chapters to a specialist book on quantum walks.
He belongs to the Division of Social Environment and Information in the Faculty of Environment and Information Sciences, and also holds a concurrent appointment in the Department of Mathematics, Physics, Electrical Engineering and Computer Science in the Faculty of Engineering Science.
Key terms
- Quantum walk
- A mathematical model, based on the ideas of quantum mechanics, that describes motion on a diagram made of points and lines
- Graph
- A figure made of points and the lines connecting them. In mathematics, graphs are studied for the structure of how their points are connected

View More ↗ResearchResearch themes
With quantum walks and discrete mathematical models as research fields, the lab mathematically investigates the relationship between the structure of a graph and the behavior of quantum walks on it. Paper titles include models that bridge random walks and quantum walks, and approximation of the discrete Schrödinger equation by quantum walks.
