This is a) fake or b) a scam.

#13Scott Aaronson is an MIT prof and a leading researcher in quantum computing. Here is his take on a recent paper DWave published in Nature: http://www.scottaaronson.com/blog/?p=639 (And the Nature paper: http://www.nature.com/nature/journal/v473/n7346/full/nature1... )
"after four years of the quantum computing community being told to review a restaurant based solely on its ice water and table settings, I’m delighted that D-Wave has finally brought an appetizer." haha... those physicists
> As some of you might be aware, I’m a theoretical computer scientist, not a physicist (much less an experimentalist).

#16D-Wave has been operating under heavy-duty NDA's for a long time. I know of at least two published authors in quantum physics who have signed an NDA and been given the grand tour. I know one well enough to have asked him what he thought without divulging anything he couldn't tell me. He said what D-Wave had when he was there was not a general purpose quantum computer, but rather, a sort of hard-coded specific purpose…

#17It's not fake, but it's not the quantum computer you would expect. http://spectrum.ieee.org/computing/hardware/loser-dwave-does... "D-Wave's system uses a chip with little loops of niobium metal containing Josephson junctions—two superconductors separated by an insulator. When the chip is cooled to very low temperatures, tiny electrical currents flowing around the loops exhibit quantum properties, and you can use the…

That said, I'm quite impressed that D-Wave is finally bringing out a thingy that actually does something. Reading the Scott Aaronson post elsewhere in this thread it appears that they've finally got around to demonstrating that their thingy really does do stuff that involves quantum mechanics.
They're still way behind their implausible schedule, and their thingy still can't do anything that a classical computer can't do a helluva lot faster and cheaper, but I do congratulate them on having a proper working thingy.
But they need to stop calling this thingy a quantum computer.

#19Is... is this real?
Ouch.

#20ok so where is the "hello world" program for this type of system? .. wonders if it could figure out the HTML5 specs before we do?
