Umm. Saying that something is quantum and it being actually quantum are not the same. Researchers MIT are still working on TRUE quantum computing. They estimate at least ten years for a serious breakthrough.
At least some scientist found that the dwave systems actually are quantum computers, but can only solve a subset of all quantum solvable problems. So it’s not a universal quantum computer, but still a quantum computer. http://spectrum.ieee.org/tech-talk/computing/hardware/scientists-confirm-dwave-computer-chips-compute-using-quantum-mechanics
I once found an article (just can’t find it anymore when i need it ..) reporting that it would be possible to port a derivate of the shor algorithm with O(n^3) on these machines. On a universal quantum computer shor has only O((log n)^3)
