I forgot to mention something else - the exact results of QC algorithms are read probabilistic from the instruments that read out the state of the machine. The confidence intervals for these results is important. I do not think that the results for every demonstration are read to 7 sigma... Be careful about this because if you are seeing a result of an exact algorithm that's read to 3 sigma then it's probably best to rate it as equivalent to a heuristic that gives a result within 0.01% 99.99% of the time (I am being generous). It's all in the small print in the annexes...
