| dc.description.abstract | Currently, existing quantum annealers have proven themselves as viable technology for the first practical applications in the noisy-intermediate-scale-quantum era. However, to fully exploit their capabilities, a comprehensive characterization of their finite-time excitations is instrumental. To this end, we develop a phase diagram for driven Ising chains, from which the scaling behavior of the excess work can be read off as a function of process duration and system size. “Fast” processes are well described by the Kibble-Zurek mechanism; “slow” process are governed by effective Landau-Zener dynamics; and “very slow” processes can be approximated with adiabatic perturbation theory. | en |
