DWave just published a paper in Nature that shows that they have built a 8 qubit quantum device. This could be legit. However even if what they say is 100% true and correct, it's still not a 'general' quantum computer, it's only wired for one kind of optimization problem, and it's only 128 qubits which will not allow you to do things current computers can not yet do. You need closer to 1000 qubits for that.
