I guess someone will eventually introduce some kind of terminology like, "qubit equivalent". But I think that if you could build an error free 128 qubit machine, this would be interesting. But the main reason I see for that is if you can build one with 128 qubits, almost certainly someone with a lot more money than you, with a black budget, can build one much larger. The basic thrust of the article, and the paper, seems to be that if you can engineer a large enough quantum computer than doesn't really work, you can simulate one that doesn't exist. It's truly great if they are right, but I can't find a single statement about this paper on the entire web by an expert that is enthused about this announcement. The paper is short enough that there should be some comment by now.
