I can try to give it a shot, however, I'm no expert and everything I write may be completely wrong. Quantum annealing is essentially a quantum algorithm for searching in O(n^0.5) (as opposed to classical computing's O(n) ) D-Wave is attempting to build hardware that can perform quantum annealing The news is that D-wave managed to perform quantum annealing The author is sceptical that this is as impressive as it sounds because there is no evidence D-Wave actually did quantum annealing with a O(n^0.5) algorithm, and in fact it appears that it was in fact slower than simulated quantum annealing (that is, a classical machine attempting the quantum algorithm, which of course can be no faster than O(n))
