If you mean in a "quantum computer" sense, no. They're slower than classical alternatives for sure, and significant entanglement has yet to be demonstrated. Even theoretically, D-Wave has yet to produce any reasons to believe the mechanism of operation is quantum in any significant way.

Remember your CPU requires quantum mechanics to explain its operation (above and beyond "that's why the atoms don't implode"), so "it does quantum things" does not a quantum computer make.

Yes, I meant it as in, "Processes qubits with entangled ensembles of photons". Thanks for the answer, it's what I remembered from the last time I'd read about them, but that was a while ago.
