Google Confirms D-Wave Quantum Computer 100 Million Times Faster Than Conventional Ones (Leo Kaas)

This post was submitted by Leo Kaas

D-wave claimed they had created a quantum computer. The reaction seemed similar to the E-Cat announcement. Now the Customer (Google) has come forward with positive results.

An excerpt:

[Google] has presented findings conclusively demonstrating the D-Wave does perform quantum annealing, and is capable of solving certain types of problems up to 100 million times faster than conventional systems. Over the past two years, D-Wave and Google have worked together to test the types of solutions that the quantum computer could create and measure its performance against traditional CPU and GPU compute clusters. In a new blog post, Hartmut Neven, director of engineering at Google, discusses the proof-of-principle problems the company designed and executed to demonstrate “quantum annealing can offer runtime advantages for hard optimization problems characterized by rugged energy landscapes.”

    Analog computers always were100 million times faster. There are many advanced technologies
    that did not gain sufficient interest in time but they are there.

  • LilyLover

    Entanglement manipulation is not achieved yet. Call it lighty or lasery computer but not the “quantum” with “qbits”. But then again difference between 3 bits and two bits is one bit, a quantum, non amorphous quantity – so, legally it is a quantum computer, just like your digital tv signal.

    George, take it from me, Google neither has a Quantum Computer, nor any functional AI. They have the departments, so, the show goes on to keep their jobs. No real efforts are made in either areas at google. It’s an Ivory tower program as of now. Self serving aggrandization.

    Usually I am more supportive of new things but this just a smoke and mirrors. Even if google has smart people, the very smart people are smart enough to pull of the pink unicorn in front of the bosses.

      LilyLover, Ha, I am not in any way thinking of Google, I have not even read the report, I am at all times referring to an accepted “Quantum computer”

  • deleo77

    It definitely was. The established quantum computing scientists scoffed at their approach. Some of them still do, and say that their machine isn’t doing anything special.

  • Zephir

    It isn’t scam – but it runs with 1000 qbits, which corresponds roughly 10-bit precision, whereas your PC runs with 64-bit precision (i.e. 2E16 x higher one). For to achieve the same precision the of D-wave calculations should be repeated 2E16- times and their 10E7 higher computational power would remain virtual only. Personally I hope, that the cold fusion runs on more robust economical grounds, than the D-wave computers.

  • Zephir

    Google says that its quantum computer can solve problems 100 million times faster than ordinary computers, but its results don’t stand up to scrutiny. https://www.newscientist.com/article/dn28641-experts-doubt-googles-claim-about-its-quantum-computers-speed There are also doubts, that the Google computers are true quantum computers by their nature, as they don’t work at true quantized level.

    Why? The computational power of classical and quantum computers must converge mutually due to common physical laws shared. From this perspective the quantum
    computing is sorta modern hype, based on willful ignorance of uncertainty principle from occupational reasons. This principle limits the computational power of quantum computers in the same way, like this one of classical ones – just from opposite side of ratio precision versus frequency.

    In simpler words: the quantum computers tend to be very fast, but of low precision,
    whereas the classical computers are kinda slow, but their precision is already much higher. To achieve the same precision of quantum computers you should repeat the results of quantum calculations multiple-times and to average the results, which would wipe out the advantage of speed. This theorem was already proved for speed of quantum communication a cryptography: the classical computers have the same limits of security, like the quantum ones.

    http://phys.org/news/2013-01-quantum-strategies-capacity-optical-channels.html

    But the actual truth is, in many applications the strict determinism of classical computers
    isn’t actually necessary, for example during optical pattern recognition you can be never fully sure with the result – after then the parallelistic approach of quantum computers could bring the advantage in speed – but for specialized applications/algorithms only.

      for now.

    • georgehants

      Zephir, you seem to be saying that only the classical reality can exist as any Quantum reality would be ——
      “Why? The computational power of classical and quantum computers must converge mutually due to common physical laws shared.”
      That is rather odd as this classical World stems completely from the deeper more complex Quantum reality.
      Rather contradictory, I think

    That should solve all those pesky legislators demanding to ban encryption on the web and in other communications (David Cameron for example). This might become the perfect tool for targeted decryption, where a subject is under reasonable suspicion and a due legal process permits decryption of their communications. This would permit the rest of us the right of privacy and the protection that it affords from those that would seek to defraud, impersonate or manipulate us.

    • Omega Z

      With the advent of Quantum Computer’s, does privacy cease to exist?

      Currently, about 100 Billion electronic interactions take place everyday & only a few 1000 people to deal with that. It’s the reason you have so many people unjustly on Do Not Fly lists & such merely flagged by computers. They do not have the manpower to check them all out. They can’t even check out all those they need to keep track of. Not even close.

      In essence, Our privacy is protected by it’s enormity. The best they can do is store all this data for analysis after the fact incident’s occurs. With the creation of a few Mainframe Quantum Computer’s, all this data can be analysed in real time.

      There are those who will argue that if you’re doing nothing wrong, you shouldn’t be concerned. I wonder how they would feel if we put them on live TV 24/7. I wonder if they would then grasp the real definition of Privacy.

    Very old stuff that most of Mathematics likes to hide but now is coming to the front of science again.

    • Zephir

      IMO Goedel theorems apply to classical physics as well, as it has trivial geometric origin. Many physical systems like the double pendulum are truly stochastic by their very nature and even the most exact simulations cannot improve the predictions of their behavior.

      • georgehants

        Zephir. interesting you seem to be comparing classical measured behaviour with the possible many infinities of mathematics.

      • Roland

        All systems are stochastic in nature when measured with sufficient precision; a straight line is a mathematical abstraction that has no analogue in a universe found to be fractal and profoundly recursive when closely examined, there are no straight lines outside our imaginations.

        Classic, Newtonian, physics was a useful approximation, quantum physics is a more useful approximation, an understanding of strange attractors and field effects beckons, and we’re still far from the end of the journey towards understanding the totality around us.

        D-Wave Systems never claimed to have built the ultimate quantum computer, just a Wright Brothers version that addresses a particular class of problems at very high speed; non the less their computer is superpositional rather than binary and requires entirely new conceptual frameworks, hardware, ‘languages’, software and input/output devices. It’s pretty different and does what it was intended to do; demonstrate a functioning commercial product that many thought impossible.

        Sound familiar?

  • georgehants

    Very interesting on this page because of the connection of our perception of reality to the Mind.
    This like many other important subjects is considered heresy by our holy priests of science.
    They declare emphatically that their is no such thing as Mind we operate solely with a grey steam engine between our ears.
    The Spanish Inquisition had nothing on the religious scientific censorship in place today.
    Thank god for the usual Rebels that think for themselves, in the case of Quantum Mind, Hameroff and Penrose et al.

    New Theory Claims Quantum Weirdness Only Exists in Our Imagination.

    • Zephir

      The quantum mechanics is not weird in dense aether model and it can be simulated with hydrodynamic analogues easily.
      But it doesn’t mean, that the quantum uncertainty limit can be broken
      in context of single deterministic observation. We can make the
      observation more classical with repeating the experiment with
      tomographic or stroboscopic arrangement and improve the precession of
      single quantity arbitrarily by averaging of results – but the remaining
      conjugated quantities will remain blurred the more.

      • georgehants

        Zephir, a rather simplified view of the Quantum Reality we inhabit I think, the superluminal etc, is not a model but a Fact hidden by science from the beginning, with the inane argument that we humans are unable to send information this way so it does not count.
        Can you think of more dead-brained thinking.
        The only other answer at present to the proven phenomenon is that the reality is in one microscopic dimension with no distance between events.
        This does not cover the point of my post regarding the connection of the Quantum computer, long denied as being possible by most of science and the still denied Quantum Mind.

    If Google gave a shot to a quantum computer, I see no reason for them to not take a shot at LENR.

    • Roland

      D-Wave’s senior partner is Lockheed-Martin…

      • pg

        Google’s senior partner is Google, they do not depend on anyone else for their decision, so if they have enough vision to go through with a quantum computer, they might have it for LENR too.

        • Roland

          This does ignore the active efforts of Lockheed to build a market for their new acquisition, beyond their internal needs, and the strong possibility that they approached Google rather than the reverse.

          Further to this D-Wave had a proven functioning technology and actually sold Lockheed a commercial system for $10,000,000 2 years prior to the company being partially acquired by Lockheed.

  • georgehants

    More correctly 99% of establishment scientists believed what their priests decreed to them, that A Quantum computer was impossible for various Dogmatic reasons.

    100,000,000, times faster than a super computer of to-day?
    That is some DEEP Thought.
    I suppose the answer is 42..

      Wrong, it is 46, Palladium

    Does this technology have any applications in Google’s artificial intelligence research? From the article it sounded like it was only good for very specialized applications. If it could help AI, it might create the first real HAL 9000.

    • georgehants

      And just like Hal it will be sent insane by some corrupt establishment change in the programming.
