I advocate for logical and consistent viewpoints on controversial topics. If you’re looking at my profile, I’ve probably made you mad by doing so.

  • The part that doesn’t make sense is how a guess on a QC in a binary is any better than a scientist just guessing an outcome from a binary. Yeah, it can do it a lot, but if you can’t test the outcome to verify if it’s correct or not, how is it better than any other way of guessing outcomes?

    Statistically, it absolutely isn’t. Even if it continually narrows things down via guesses, it’s still no more valuable than any other guesses. Because in all the whitepapers I’ve seen, it’s not calculating anything because it can’t. It’s simply assuming that one option is correct.

    In the real world, it’s not a calculation and it doesn’t assist in… anything really. It’s no better than a random number generator assigning those numbers to a result. I don’t get the utility other than potentially breaking numerical cryptography.


  • So that’s the part that gets me stuck. There is no clear answer and it has no way to check the result as QC aren’t capable of doing so (otherwise they wouldn’t be using QC since they can only be based on binary inputs and binary guesses of true / false outcomes on a massive scale). How can it decide that it is “correct” and that the task is completed?

    Computations based on guesses of true / false can only be so accurate with no way to check the result in the moment.


  • I appreciate the reply!

    I made the attempt, but couldn’t parse that first link. I gathered that it was about error correction due to the absolutely massive number of them that crop up in QC, but I admit that I can’t get much further with it as the industry language is thick on that paper. Error reduction is good, but it still isn’t on any viable data, and it’s still a massive amount of errors even post-correction. It’s more of a small refinement to an existing questionable system, which is okay, but doesn’t really do much unless I’m misunderstanding.

    The Willow (and others) examples I’m skeptical on. We already have different types of chips for different kinds of operations, such as CPUs, GPUs, NPUs, etc. This is just one more kind of chip that will be found in computers of the future. Of course, these can sometimes be combined into a single chip too, but you get the idea.

    The factorization of integers is one operation that is simple on a quantum computer. Since that is an essential part of public / private key cryptography, those encryption schemes have been recently upgraded with algorithms that a quantum computer cannot so easily unravel.

    With quantum computing, a system of qubits can be set up in such a way that it’s like a machine that physically simulates the problem. It runs this experiment over and over again and measures the outcome, until one answer is the clear winner. For the right type of problem, and with enough qubits, this is unbelievably fast.

    Problem is, this only works for systems that have a known answer (like cryptography) with a verifiable result, otherwise the system never knows when the equation is “complete”. It’s also of note that none of these organizations are publishing their benchmarking algorithms so when they talk about speed, they aren’t exactly being forthright. I can write code that runs faster on an Apple 2e than a modern x64 processor, doesn’t mean the Apple 2e is faster. Then factor in how fast quantum systems degrade and it’s… not really useful in power expenditure or financially to do much beyond a large corporation or government breaking encryption.


  • Well, I love being wrong! Are you able to show a documented quantum experiment that was carried out on a quantum computer (and not an emulator using a traditional architecture)?

    How about a use case that isn’t simply for breaking encryption, benchmarking, or something deeply theoretical that they have no way to know how to actually program for or use in the real world?

    I’m not requesting these proofs to be snarky, but simply because I’ve never seen anything else beyond what I listed.

    When I see all the large corporations mentioning the processing power of these things, they’re simply mentioning how many times they can get an emulated tied bit to flip, and then claiming grandiose things for investors. That’s pretty much it. To me, that’s fraudulent (or borderline) corporate BS.


  • Yeah, most quantum science at the moment is largely fraudulent. It’s not just Microsoft. It’s being developed because it’s being taught in business schools as the next big thing, not because anybody has any way to use it.

    Any of the “quantum computers” you see in the news are nothing more than press releases about corporate emulators functioning how they think it might work if it did work, but it’s far too slow to be used for anything.

    I generally don’t talk about it, but because you asked, I have seen a lot of anime and hate most of it. I have seen Hellsing, Hellsing Ultimate, about 9/10 of the OG run of Fullmetal Alchemist, a lot of Ranma 1/2, Serial Experiments Lain, Akira, some Death Note, La Blue Girl, some tennis one I can’t remember the name of, Castlevania, a few Studio Ghibli movies, Attack on Titan S1 & 2, random episodes of Samurai Pizza Cats, all of One Punch Man, Interspecies Reviewers, Slayers, some DiC Sailor Moon, some early Pokemon, and a few Dragonball, YuGiOh, Digimon, and Naruto episodes.

    I don’t count early GI Joe or Transformers even though they’re technically anime, but I didn’t like those either.

    Of those, I liked Interspecies Reviewers, about 1.5 seasons of OPM, 1 season of Castlevania, and Hellsing Abridged (because it’s fucking hilarious).

    Here’s a random top 10 of reasons:

    1. Anime has a horrible habit of having a great premise, a lot of repeated setup, and then zero payoff followed by a new season escalating with the same. In short, great at premise, poor at developing it into a story. And endings? They have no idea how to end a series except for fighting bigger bad guys…
    2. And that’s IF they can even be arsed to finish a series. I’m aware of the timeframe dynamic between manga and anime. It fucked over Game of Thrones too. Maybe we just agree not to start a show before the source material is done?
    3. Much of the animation looks abysmal and the “serious” ones seem to have an awful habit of just… panning over a background or frozen characters in a scene for fucking ever to fill time. I made note of this during Serial Experiments Lain to my friend who was making me watch it and it basically ruined the show for him. It completely wrecked the pacing and was done CONSTANTLY. There were 45 second pans (which I would start audibly counting after 10 seconds) while the main character just monologued “I’m 12 and this is deep” bullshit that was nearly completely disconnected from the plot. There was no reason to do this. Even recent shows like Castlevania did this.
    4. Shit just happens that doesn’t make any sense in context of the world they’ve set up. This is endemic from anime I’ve seen. Anime fans think that randomness is “creative” instead of just “throwing shit at a screen because the writer had a fever dream and it doesn’t matter at all if it makes any fucking sense”. Spirited Away is basically just this. No, randomness is not creativity, Katy the Penguin of Doom.
    5. They’re just a different set of tropes than American cartoons, many of which I find to be nonsensical, twee, or cringe-inducing. Bloody nose when you get a boner trope, I’m looking at you.
    6. I fucking hate Japanese voice acting (and often for the most part the Americans who dub it, especially in kids shows). This started when Sailor Moon came over and I wanted to kill everyone in the immediate vicinity whenever most of the characters spoke. That shrill panic screaming that was in SM and Pokemon was awful.
    7. In the same vein, I also can’t stand constant “reaction sounds”. Someone saying something mildly surprising that you should have easily realized 10 episodes ago isn’t an excuse to stare blankly and make an “AH”, “OH”, or “UH” noise (sometimes followed by a small choking sound) roughly four hundred times per episode. Humans don’t do this.
    8. They make movies that just do random shit and don’t have anything to do with the show (if not outright contradict the show). Dragonball is especially notorious for this.
    9. A really weird number of them throw in Nazis seemingly at random, appropriate time and setting be damned. Need a bad guy? Fucking Nazis!
    10. I am constantly inundated with friends that like anime telling me that I should watch whatever their new anime obsession is despite it conforming to 3/4 of bad things on this list because obviously I just haven’t watched the right anime.
