A new study claims that the D-Wave quantum computer is no faster than the PC on your desk, leading many to proclaim the technology as overhyped. Trouble is, the performance tests were too easy and not a true measure of what these machines are capable of doing.

The D-Wave 2 is a much-hyped quantum computer, but, as scientists now report, it's not actually any faster than a regular old PC. Wait, didn't we say it was 3,600 times faster just a few months ago? Yes, and both are right. Whether one computer is faster than another is actually a mighty complicated question.

D-Wave's quantum computers have certainly demonstrated that they're capable, but they've also received much criticism from scientists. Now, new results show that their technology could be even more solid than they'd claimed in the past.

There's been a lot of talk lately about how close we are to quantum computing for the masses. Now, Canadian company D-Wave claims to have done it with their D-Wave One. Except, of course, that commercially-available really means millionaire-available.

The quantum computer that many—us included—doubted would ever materialize showed up yesterday. However, I think it's fair to say that we're a little disappointed with what actually materialized. Sure, the hack thing to do is to praise its ability to solve Sudoku puzzles, but to me there's quite a difference between…

Propellerheads at D-Wave are saying they've developed the world's first quantum computer, and the wild thing is they say they're going to show it actually working next Tuesday. Hey, wait a minute. This first foray into the strange-but-maybe-true world of quantum mechanics wasn't expected by scientists until 20 years…
