They say: Based on the results presented here, one cannot claim a quantum speedup for D-Wave 2X, as this would require that the quantum processor in question outperforms the best known classical algorithm. This is not the case for the weak-strong cluster networks. This is because a va- riety of heuristic classical algorithms can solve most in- stances of Chimera structured problems much faster than SA, QMC, and the D-Wave 2X. But that in my opinion does not mean that it is not a quantum annealing computer, just that it does not bring the speed-up we are looking for.
