The paper is pretty accessible:

The money quote:

"a D-Wave computation is both quantum and analog, with nothing resembling a discrete instruction or basic operation that can be counted"

So it's not really a quantum computer at all in the sense that the term is usually understood nowadays. It's an analog computer. And if you believe Scott Aaronson (and I do) it's a classical analog computer.
