A fully connected quantum annealing architecture;
Sci. Adv. 1, 9, e1500838 (2015)
Quantum computers show the potential of outperforming classical computers in a variety of applications. We are interested in developing algorithms for solving relevant practical problems, ranging from the simulation of quantum many-body systems to the solution of NP-complete optimization problems. Besides gate-based quantum computers, we also investigate adiabatic quantum optimization and quantum annealing.
