back to article D-Wave opens up access to small-scale Advantage2 quantum computer

D-Wave Systems has put its next-generation Advantage2 quantum computer into the cloud, or at least some form of it. This experimental machine will be accessible from D-Wave's Leap online service, we're told. We first learned of the experimental system last year when the biz revealed its Clarity Roadmap, which includes plans …

    Cloud hosted prototype = digital computer?

    Wait, is this "prototype" a physical thing, or software running on a cloud cluster of *digital* computers?

    >> "By making the Advantage2 PROTOTYPE available in the Leap quantum cloud service today, the company is providing an early snapshot for exploration and learning by developers and researchers,"....

    If they define their *software* implementation as a "prototype", they can happily sell people access to their software running on digital computers while claiming it is access to a "quantum computer PROTOTYPE". Since there will likely be only one physical prototype, and it is likely buggy and problematic (aka a 'prototype'), you would not offer *that* to customers. You'd constantly be configuring your only prototype, cooling it to superconduct, warming it, measuring the result, get buggy impossible prototype results the customer won't pay for, restart... very slow, not the sort of thing that scales to a remote service. On the other hand, DWave's "classical" solver and the digital computer cluster that it runs on is trivial to scale, and already offered via its Leap service.

    Leap offers the digital cluster as either "classical" or "hybrid" now. I wonder how many of those "hybrid" solver problems are dispatched to an actual quantum computer.... I bet its only a token number.

    If we open that cloud, is Quantum Computing alive or dead?

      Dead. To-reiterate:

      Take a property, like circular polarization (it's a sort of spiral-like spin in the path of light),

      Suppose circular polarization is an apparent net motion between two oscillations. One of the photon (p1) and one of the detector (d1). Lets suppose net(p1,d1) is a circular polarization component in the xy plane.

      A different detector, d2, has a different oscillation pattern, with respect to d2, p1 is not spinning in the xy plane, it might be spinning in a different plane. net(p1,d2) is a different circular polarization to net(p1,d1)

      A third detector, d3,has a different oscillation pattern: with respect to d3, p1 maybe has no circular polarization at all. i.e. net(p1,d3) is again different.

      So, our photon has many possible circular polarizations, it has net(p1,d1), net(p1,d2), net(p1,d3).....it is interacting with the matter around it, so it has many possible net properties.

      Now suppose it is absorbed by detector d2. net(p1,d2) will now dominate, it appears as if the act of "measuring" p1 with d2 caused it to now have a definitive circular polarization of net(p1,d2).

      Yet it didn't, it always had a very simple oscillating pattern (lets call that pattern "F1") and the detectors, and all matter around it, also have a very similar simple oscillating pattern, ~integer multiple of F1. You didn't set anything, because you never measured that photon, you only ever measured the NET EFFECT of the photon on the particular detector it struck.

      Now suppose we pretended that "circular polarization" is a property carried ENTIRELY by the photon, that the photon has some magical composite of net(p1,d1), net(p1,d2), net(p1,d3)..... in all these possible states until you measure it.

      You might model that, as Schroedinger did, and you would have a very useful engineering model, but a terrible understanding of matter. A model filled with impossible magical distance and time effects, you'd see net "shutter effects" (like how the spokes of wheels appear to be going backwards in a stroboscope) as if time was travelling backwards. You'd model particles travelling backwards in time, that are actually net effects only appearing to go backwards in direction.

      So many ridiculous, impossible things, because you simply didn't realize you were looking at a net effect.

      So, anyway, about your qubits.....

      That is misleading to an inordinately unfortunate degree, AC, however quite understandably necessarily so if/when the primary ultimate aim is for novel progress to not fundamentally disrupt and overturn and destroy inequitable status quo programming modules ...... for whenever the cloud hosted Advantage2 prototype has software for running cloud clusters for/with digital computers, is IT a Metaphysical AI thing and a model much like you suspect and have reiterated admirably succinctly upon but filled with innumerable magical spooky at a distance and timely effects rather than loded or coded with anything impossible to provide.

      And quite perfect enough it be for all manner of matters into exercising with means and memes pioneering Quantum Communications Leaps ....... for Consolidating Revolutionary Existential Advantage.

      That's what we use IT for here experimenting initially/primarily with El Regers both either autonomously able and/or subsequently enabled and assisted to effortlessly exhibit a grand mix of many dark and deep talents ....

        And no matter how strangely spooky and timely coincidental as it may seem, and such similar enigmatic non-paradoxical parallels are a sure enough sign of the emergence and hardening reinforcement of Advancing IntelAIgent Singularities, much of the above is mirrored/reflected and refracted in the view presented via HPE Insight AIOps championed by Ronak Chokshi, and reported here on El Reg by Joseph Martins Thu 16 Jun 2022 // 15:00 UTC in a SPONSORED FEATURE beginning ..... AI isn't magic. But applied correctly it can make IT infrastructure disappear.

        And that is sure-fire evidence of Significant Advanced Progress in Quantum Communications Fields already having been made/taken/deployed/employed/exploited.

        It is though not something you were not earlier clearly advised about, even should it now still surprise you and be any present current cause or course for mounting misguiding concern .....
