back to article D-Wave deploys first US-based Advantage quantum system

Quantum computing outfit D-Wave Systems has announced availability of an Advantage quantum computer accessible via the cloud but physically located in the US, a key move for selling quantum services to American customers. D-Wave reported that the newly deployed system is the first of its Advantage line of quantum computers …

    But what if?

    The computer in the USA is quantum entangled with one back in Vancouver?

    physically located in the US

    Probably, - unless you try and measure its momentum

    Amusing that they've adopted the phrase "Leap quantum cloud service", reminding us of "Magic Leap", who were/are another bunch of scammers promoting technology which didn't do what they said it did.

    SPCA is investigating D-Wave

      The rumours are both true and false - until you examine them.

    Enquiring minds and all…

    An interesting article, or response from a like minded regmind, would be to explain what current business problems these new fangled quantum computers are solving that traditional 1 and 0’s can’t. Or is it it a case of the blockchain replacing shekels, because we can and everybody mining their own cool shells on the beach is having an impact on the environment…

      They *are* digital computers.

      It's a hybrid solution, your problem goes to a switch that hands it to a cloud of digital solvers or a DWave box. Whichever is more appropriate.

      Quantum computers take hours to setup, cool to superconduct, warm up again. They're finnicky and may need multiple runs. They give answers in hours or days. You would run them only out of curiosity, to see if it can obtain a more optimal solution than digital optimizers (if they actually worked the way Feyman imagined a QM computer would work, they'd always return the most optimal result, sadly none of that shit is, or was ever, real. And they do return sub-optimal results).

      Even if you planned on running it on the Quantum box, for marketing purposes, you'd still run the digital solver, get an answer in seconds or minutes just in case the answer is a better solution. The last thing you'd ever want to do, is return an answer to a customer, where the customers own optimizer returns a more optimal answer. If that happened, your game is up, your marketing BS is revealed! Better to also run it on all stock digital solvers as-well to avoid said issue, and return the most optimal of all of them.

      I hate this scammy crap, it annoys the hell out of me.

      Why not just sell the cloud digital solver? So the customers knows you're delivering the best price, max scalable, best algorithms of the day. And not, say, intentionally running a crap algo like "simulated annealing" just so you can sell them a bit of overpriced hardware that runs simulated annealing faster. A risk with a company that wants to sell something other than the product it's selling.

      If you don't understand the main use case for a Quantum Computer its this:

      A solver is used to solve problems of the form:

      X = Funct(A,B,C,D,E,F,G,H,I,K......)

      Find the value of A, B,C,D... for which the function Funct returns the minimum (or maximum) value.

      For complex, non-linear systems, often systems derived from real world data, you cannot solve these algebraically. Simply trying brute force limits for each of A, then B, then C, etc. rarely works. Testing all possible values is not possible, there are just too combinations. In addition there may be constraints, e.g. C may only be valid in the range 0 to 1. Worse, when you get to my stuff, you get complex constraints too. e.g. The limits of C depends is some function of E and F.

      Solving these is non-trivial, and an entire branch of Math and algorithms.

      You could imagine a quantum computer (if it actually worked like Feyman imagined) could solve public key encryption this way.

      e.g. X = GrammarCheck(DecryptFunct(EncryptedMessage, A,B,C,D,E,F,G.....))

      Find the values of A,B,C,D... that returns the max X, so run a decryptor to find the private keys (A,B,C,D...) that decodes an encrypted message to grammar correct readable text.

      You could even test it if you have a test sample and know the result.

      e.g. X = CompareForSimilarity(KnownRealDecrypted, DecryptResult(EncryptedMessage, A,B,C,D,E,F,G.....)))

      Find the A,B,C,D.... for which X is the minimum, i.e. closest to your known text, then check the A,B,C,D... keys against your known keys (because you're doing a test and did the encryption) and see if it actually found the result.

      BUT THIS DOES NOT WORK, it does not work because the core basis for a Quantum Computer is bogus, bunkum, a faulty piece of Science. An approximation model of a system, not the actual system.

    Let's hope they still use digital legacy kit...

    For the billing at least. Something has to be predictable.

    Quantum as 'marketing brand'

    Is it actually the hardware? Do they actually offer you a quantum computer on that cloud? Or is 'quantum' in that context simply a marketing term for, say, something like distributed CMAES running on digital computers?

    Stuff like saying "you don't need to fit the qpu. The hybrid system will choose automatically", are a big red flag that their offering is a cloud cluster solver on digital computers. Of course you'd have to fit the qpu to be running on a quantum computer.

    They use some very fuzzy language there in that Leap marketing. "Hybrid approach"

    "Leverage our advanced algorithms to choose the best way to solve your problem [between a quantum computer and a cluster of digital computers]."

    'So, gee, we could run this on this cluster of solvers NOW and give him an answer in seconds, or we could configure the target-function in electronics, then spend a few hours cooling the coils down to superconduct, then warm it up, and maybe do a few runs because its a bit hit and miss. '

    I'm guessing that algorithm always chooses the cluster of digital computers, right? Maybe a contrived token run on a Dwave system, every now and again to qualify as hybrid?

    Call me cynical, but I think their offering is all "quantum" as a brand now for digital solvers.

    DWave attempting to confuse the customer as to what they are actually paying for by labelling it "hybrid" when the reality (like problems bigger than their hardware can solve) would suggest it is just a digital solver.
