    Well... there's only supposed to be one Dong in a Poosay, but sometimes you'll hear about two Dongs in a Poosay. Probably has something to do with .. er.. inflation.

    Just to put a finer point on this...

    Google is investing in a QC platform that can not compute anything useful. Martinis's group has a 3 qbit (entangled) device IIRC.

    So if the 512 Qbit(entangled?!) D-Wave device is worth something. Then evidence suggests they don't need a QUBO solver as there's little reason to throw money into something that is so far from productive when you have something that (allegedly) works sitting on your premises...or of course D-Wave could simply be useless.

    Seems to me they're hedging their bets. The intel 4004 equivalent has not yet been constructed

    You don't hedge if your bet already paid off.

    In the same sort of sense that a hole is a positron.

    If we really do live in a multiverse, it's entertaining to consider what happens to the law of conservation of momentum. Obviously, the reason I'm even mentioning this is as a way to build a hoverboard, visit moons, planets and stars, and have free energy on demand. But you knew that.

    Anyway, back to the plot...

    Oh. Bad idea. Momentum is conserved in every 'verse over that 'verse.

    Back to the drawing board.

    Posted By: Andrew PalfreymanMomentum is conserved in every 'verse over that 'verse.

    So what keeps momentum from leaking out of one 'verse into another one? Is this barrier an absolute barrier to travel between universes, since anything physical would bring its momentum with it, decreasing total momentum in the origin and increasing it in the destination 'verse?

    I think it means that the membranes are pretty impermeable.
    Oh. hang on. There could be equal and opposite flow. Zero divergence, I mean

    "No quantum computer is ever going to fit into your pocket, because of the way qubits need to be supercooled (unless, of course, someone uses a quantum computer to design a better qubit)." And that's what's meant by bootstrapping. We routinely use computers to design better computers and better transistors for them.
