      I 100% agree about the lack of a clear explanation, and I have always believed the old maxim, if you can't explain it clearly, you don't really understand it.
      The only reservation I have about not continuing to pursue it is that it may be one of those things in science that are not linear and one day there is a massive advance in the field which reaps great benefits.. However, at the moment, it doesn't seem to be clear where it's heading at all.
      On the matter of the super position collapsing once it's observed to a binary value, that's the first thing I wondered when I was told of the concept of the Qbit; that at some point the data will end up being represented as a function of boolean algebra.

    I don't know if anyone else has mentioned this but quantum computing _could_ speed up the internet a little and maybe moderately by improving packet routing.

      Maybe so, @Bob Ross. That was kinda part of my statement, wasn't it?
      You never know what kind of clever algorithms someone will come up with, though. Have you seen the lengths people go to to find HW and SW bugs? Would it have occurred to you to write to the memory rows on each side of a row to change the data in the target row? And that's a fairly obvious one once you hear it. (The actual implementation of Rowhammer is pretty complex, as I understand it, though.)
      Yes, I see what you're saying about needing to know what's going on to figure out the best route but who knows what will come up?

    @jehl1963 ปีที่แล้ว +10

    Very interesting and well presented. Having been a "Travelling Salesman", and managed inventory in warehouses, I think I'm qualified to provide a real-world response to the idea of using quantum computing to calculate the ideal solution to those problem. Yes, it can and and will do so, "...but at the end of the day..." it's most likely not going to make a world-changing improvement? Why? Because of diminishing returns, and the corollary to the idea of "diminishing returns", which is "other factors".
    Diminishing returns: Having planned my daily sales routes using different software packages, I quickly came to the conclusion that it is far simpler -- and just as effective -- to avoid planning bad routes. Mathematically -- if there are N! possible routes for N stops to be made, there are usually just a few "bad" routes. For example always moving from one stop to the furthest available next stop. Don't do that! Once you have eliminated the bad routes, the rest of the routes often have very similar values, and the downside risk of picking any of them is very small. So "at the end of the day", it doesn't matter which you pick since the difference between them may only be a few minutes of travel time. And given that any particular customer visit may have a variance of 10-15 minutes, saving a minute in travel time will not make a difference in the time that you arrive back at the hotel at the end of the day.
    This brings me to the "other factors". In a world where optimization yields diminishing returns, other factors can quickly trump the benefits of sophisticated optimization techniques. In the example given above, a talkative customer, or maybe some unexpected news of a potentially big deal (which is why I was visiting customers in the first place!) may cause me to chuck my day's plan in order to spend more time with that customer. In the case of warehousing, you may spend countless hours calculating the ideal locations for parts based on their size, weight, value and projected activity level, only to be faced with stocking the next fad product (Look! Pet rocks! A Mood ring! Slime!!!) which will suddenly cause you to throw the whole scheme out and start again. It is impossible to predict the next fad product, in either the commercial realm, nor in industrial products. There is a world of unknowns out there waiting to jump up at some unpredictable time and ruin your ideal solution. So maybe the best solution is to not get too heavily invested in any solution, and instead focus on avoiding the stupid solutions. This could be summed up by saying "Just don't do anything stupid". There are evolutionary benefits to just not getting yourself fired/killed/eliminated, and living to fight another day.

    Thanks, it is an excellent video. As in many new technologies, the press tends to over-promise. Could you comment on the applications of quantum computers in machine learning? I understand that methods based on Grover's search algorithm which has been shown to solve unstructured search problems with a quadratic speedup compared to classical algorithms. Another exciting topic is Quantum annealing for optimisation is not a universal quantum computer but many engineering problems are optimisation problems.

    Such a great coverage of the so-what of quantum computing for technical people who aren't physicists, and appropriately humble as to the certainty of the perspective. Instead of being mired down in the technical details of how quantum computing works, this video gives enough of an idea, but focuses on professed applications to be skeptical of, applications to be hopeful of, as well as how the exploitation of quantum computing will likely manifest itself initially.

    When I was introduced to TeX and LaTeX (mid to late 1980’s) my professor told me it was pronounced “LAH-tekh” and that’s how I’m used to hearing it pronounced. Checking the Wikipedia page, “LAY-tekh” is also listed as an acceptable pronunciation, but I think Sabine is the first person I’ve noticed pronouncing it that way. I wonder if there will be a shift to this “new” pronunciation like the shift of GIF to JIF.

    • @sabinrawr
      @sabinrawr ปีที่แล้ว +2

      JIF has never been correct! 🤡
      But seriously, I do think it comes down to the fact that, in English, a hard G usually precedes a short I like "gig" and "gift"), while a soft G usually precedes a long I (like "giant" and "angina").
      So the best case for a J sound is if it sounds like JAIF, and I hope we can agree that sounds weird.

    • @jpe1
      @jpe1 ปีที่แล้ว +1

      @@sabinrawr I realize now I wrote GIF and JIF backwards from what I intended. When the GIF standard was first published I was still in college and I distinctly remember reading the documentation stating that it was “pronounced jif like the peanut butter” (“Choosey developers choose Jif” was a joke back then). But developers sometimes loose control of their works, including pronunciation (for example, see Linux) and I agree with you that a hard G, like the G in Graphics (since that is what the G stands for) is reasonable, and certainly has become the common usage.
