  We report the Atos Q-score for D-Wave's quantum devices, classical algorithms
and hybrid quantum-classical solver. Computing the Q-score entails solving the
Max-Cut problem for increasingly large graphs. This work presents the first
computation of the Q-score on a quantum device and shows how these quantum
devices compare to classical devices at solving optimisation problems. We use
D-Wave's standard methods out of the box with a time limit of 60 seconds. The
Q-score for D-Wave's 2000Q and Advantage devices are 70 and 140, respectively.
The Q-score for two of D-Wave's classical algorithms, based on tabu search and
simulated annealing respectively, are 2,300 and 5,800. Finally, we report the
out-of-the-box hybrid approach to have a Q-score of 12,500.
