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)
I’ll go back to my previous postulate that while the NSA might have hardware to do it, they don’t have the right brains for it to matter. I’m not a mathematician, I’m an engineer. I know from working with mathematicians that encryption is still secure for a majority of workable solutions. The NSA is hitting low hanging fruit right now. Look at black hat for industry clues. Working for the NSA is to black hat what snitching is to criminals. It might be lucrative, but you put yourself out of the community.
