I'm quite confident by the press release alone that these systems are still almost entirely useless for breaking crypto BECAUSE of the fact we're hearing about them. If IBM had a chip that could fundamentally break crypto, the US government would almost assuredly immediately embargo any mention of it. Sure a lot of the science behind it would likely be in public journals, but as we approach a point in which it could actually break * crypto, it would become a state secret.

I have no doubt the leaders of IBM are well aware of that fact (as well as google, d-wave, the University of Science and Technology of China, etc).
