Considering that we're still at 15 as the largest factorized number with Shor's alg. on a physical QM, the fact that these companies exist at all is quite absurd tbh. IIRC there are also no useful ML algs. known in BQP\P, and all the quantum-simulated annealing stuff that works on noisy "QM"s doesn't seem to be a big win. With this context, these "QM" companies are in reality, selling tech. that's even less capable than a vacuum-tube computer (much less a transistor calculator). Unless you care about simulating the hardware they have (for some reason), in which case it has "quantum supremacy" (lolz).
