There is a slight of hand that goes on. The QC solutions are touted in comparison to the challenge of generating an optimal/exact solution. In reality there are many heuristic algorithms that generate solutions that are with 1% of the optimum 99% of the time (choose your numbers - could be 0.1/99.9) It's also important to realise that the process of reading the solution out of a QC is probabilistic, so although the solution might be exact, the noise in the bits you are reading from means that you might have some error there... It's exciting, people have a job doing it, they are trying to do science... marketing people try and market it as valuable and no one wants to rock the boat as they will be pushed out and the science will stop.
