Comment on Performance of quantum computer no better than ordinary PC, say analysts

Comments

What's the definition of "ordinary PC" being used? Not finding an answer to that in the article, which makes it difficult to get an idea of what the researchers are comparing this thing to.

One which doesn't exploit quantum-mechanical principles of computation.

So is that a brand-new Dell XPS machine? Is that my aging-not-too-well Compaq Presario 1210 with a Pentium? Is that a Macbook Air? Is that one of Oracle's $200,000 M-series servers? Is that some beige-box piece of junk that the researchers found in their neighbor's backyard? The category "personal computers which do not exploit quantum-mechanical principles of computation" is so mind-bogglingly vast that such a description alone is hardly useful.

Wouldn't that be a classical computer? PC is a weird term to use here.
