The Tanaka Laboratory at the Department of Applied Physics and Physico-Informatics is engaged in research on quantum annealing and Ising machines in the field of cutting-edge quantum computing. This research is applied to a field called "combinatorial optimization." "Combinatorial optimization" is utilized in everything from everyday applications like schedule optimization to large-scale industries such as smart city planning and semiconductor integrated circuit design. This video provides a clear explanation of everything from the fundamental concepts of quantum annealing and Ising machines to their future potential.
