Quantum annealing using vacuum states as effective excited states of driven systems

Quantum annealing using vacuum states as effective excited states of driven systems

For hard Quantum Annealing problems, starting from the ground state might result into high failure probability due to nonadiabatic transitions where the quantum system leaves the ground state. Here, the authors propose an "excited-state" quantum annealing where a driven system starts in it...
