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…
Strategies for optimizing double-bracket quantum algorithms
Li Xiaoyue, Matteo Robbiati, Andrea Pasquale +4
Recently double-bracket quantum algorithms have been proposed as a way to compile circuits for approximating eigenstates. Physically, they consist of appropriately composing evolut…
Double-bracket quantum algorithms for high-fidelity ground state preparation
Matteo Robbiati, Edoardo Pedicillo, Andrea Pasquale +13
Ground state preparation is a central application for quantum computers but remains challenging in practice. In this work, we quantitatively investigate the performance and gate co…
Quantum dynamics of dissipative Chern insulator
Jilian Zhong, Xiaoyue Li
For open quantum systems,a short-time evolution is usually well described by the effective non-Hermitian Hamiltonians,while long-time dynamics requires the Lindblad master equation…
