I think it wasn't that long ago that supposedly D-Wave built a working quantum computer. I think that the problem lies in people having programmed computers on x86 architecture forever.

Also, just because it has partial quantum behaviour doesn't really make it a true quantum computer, I have a feeling that this news is the same.
By the time anything of this significance hits the press, it would have already been working for quite some time, and yet we don't see any evidence of any cryptographic redundancies of the scale of RSA, SHA etc.
