However, if you read the article (which I did), they are doing real engineering. They are building very sophisticated superconducting quantum circuits. Their second generation machine has four times the qubits and cycles much more quickly. This is very difficult and advanced work, and they are making it happen.
So why is DWave getting so much flack on Slashdot? Somehow I doubt it's because there are vast number of quantum physics types just waiting to display their deep knowledge whenever the subject comes up. What I see are Slashdot Pundits: hoards of pseudotechnical wanna-be's who pile on with meaningless criticism. The motivation is not to have a useful debate but to pretend to be smart by talking trash. Maybe they impress each other, but from my vantage point it looks like a lot of eight year olds shouting curse words they don't understand and giggling over how cool they are.
