This is absurd. That's a comment on a blog post, proposing a bombastic title, "Better than Shor". I'm pretty sure if they could get anywhere near Shor using their architecture they'd get more than a sympathy Nature paper.

The truth is, D-Wave has done nothing to foster the coherence of their "qubits", and so they have built a very expensive, superconducting, classical computer. There is no quantum trick, actually. You have a system of buckets and you adjust the pipes and pumps between them so that in steady-state the water levels solve some problem you program in (with the pumps). Then you start in a random configuration, turn on the earthquake machine for a bit of randomness, and end up in the "ground state" solution.

The exponential speedup of quantum algorithms is sketchy enough: good luck performing an N-qubit logic gate, or in assuming that it's your favorite black-box that need only be executed a polynomial number of times (every quantum computing textbook uses their own set of universal gates). But these guys aren't even trying.
