    BBC News: Quantum computing is finally here...

    Or is it...?

    Very interesting article either way.

    BBC News - D-Wave: Is $15m machine a glimpse of future computing?

    I object to the article...it claims it is 150 times colder than the vacuum of space....the vacuum of space is 3 degrees Kelvin. 0 Degrees kelvin is absolute kelvin is about as cold as it will get according to science....not sure what temperature these guys are hitting for it too be 150 times colder than 3 Degrees K

    Obviously not using the Kelvin scale then What's the relative tempurature in Celsius or Farenheit?

    Keep reading... It's cooled to 20 miliKelvin or 0.02 Kelvin. That's precisely 150 times less than 3k (in celcius that's -273.13 Degrees).

    The article tells us the temperature:
    "At a high level, we know what the machine is doing: namely, it's doing annealing to the ground state, with superconducting Josephson junctions (paired superconductors) at 20mK (milliKelvin) temperature, in a way that's 'mostly classical' but that has some quantum effects present, at least at the local level," says Prof Aaronson.
    edit: whoops mistyped this

    Also gotta question your statement that 0 degress K is as cold as it gets. The coldest temperature we have produced is 100pK:
    Orders of magnitude (temperature) - Wikipedia, the free encyclopedia
    100pK is still warmer than 0K...

    and I agree, it would help if I finish reading the article. I miscalculated is all!

    I thought Apple would be the first to come out with a Quantum Mac... because y'know... they're innovative and everything they do is perfect...

    Also the main question I want to ask is can this run Crysis on full settings?

    Wow..don't over estimate its ability!

    funny

    Seriously though, we're talking quantum supercomputers here, we're a generation away from personal computing.

    A laptop cooled to 20miliKelvin. Makes a change from the heat burns of todays models

    Haha! Could you imagine the freezer burn instead?!

    I'm pretty sure with cooling systems like that if you implemented them in any desktop/laptop the room the user is in would be extremely cold and may even kill them. They could always use a type of liquid cooling I guess but at the moment I'm pretty sure all we can possibly use are fans. I don't know the actual way they are cooling the computer in question but I guess that's going to be one of the hardest tasks to achieve.
    @ICTDirect_Dave, I could be wrong I'm no expert but I'd guess for hardware like this to be placed into a laptop form factor you're looking at a few hundred years away! Plus why would a end user benefit from using a Quantum computer to load up excel and do a spreadsheet! I'd be amazed if they ever release Quantum computing to the public it will probably be used as major servers in Google, Weather Analysis and Scientific Projects, I think it's highly unlikely we will ever see a quantum computer on the shelves to buy!

    There's been a lot of back and forth over the D-Wave machines, as they're very secretive about how it works, but the general consensus is that it isn't a quantum computer in the full sense of that term, but a computer taking advantage of certain quantum properties (as the article says). It's also not necessarily any better than a classical computer.

    If you explained the iPad to someone in 1975 (when the Altair 8080 was released) I'm sure they would have said the same. It's been barely 4 decades!


    A bigger question - is there actually any evidence quantum computing will speed up computations over traditional binary? Skim reading the article suggest their implementations doesn't. So what's the point?
