the use of 'quantum' appears to be tagging onto the potential of quantum annealers (which have repetitively [1] [2] been shown to be classically tractable) while trying to mimic a kind of quantum tunneling, ie the annealing schedule, without any kind of promises about exponential speedups etc. Quantum annealers themselves have few promised advantages for general combinatorial optimization problems without significant changes to extant hardware paradigms [3]
there's still a long road to commercial applications but today's hardware is simulating quantum systems beyond the scale of classical methods, for example [1]; an interesting line of work opposite to this can be found in those who improve classical methods towards such examples [2], but these are only developed because of the existing quantum hardware
Really though, today's IBM hardware is good fun to play with, eg for generating moderately large GHZ states
