Role of Riemannian geometry in double-bracket quantum imaginary-time evolution
René Zander, Raphael Seidel, Li Xiaoyue +1
Double-bracket quantum imaginary-time evolution (DB-QITE) is a quantum algorithm which coherently implements steps in the Riemannian steepest-descent direction for the energy cost…
