| Quantum computers can be a big step towards a further advancement of our technology. There is already an available generation of the first adiabatic quantum annealers. The crucial question is how quantum and how adiabatic these prototypes are. We study the dynamics of the quantum Ising chain and investigate different quantities. We discuss probabilities of obtaining correct results from the exact dynamics via the Landau-Zener formula concerning the annealing procedure. |
