    Thanks so much for putting time and resources into making these videos. I'm not a tech-savy person; I'm definitely not a physicist (I have advanced degrees in English, and a perpetually unfinished PhD dissertation). I've wanted to understand quantum computing, but the videos I've seen on UA-cam have, until now, left me bewildered. People either suck at explaining this, or they smuggle into their videos all kinds of conspiracy theories about D-Wave working in cahoots with alien demons who, being capable of altering history, reverse-engineer trivial cultural artifacts that are curiously exclusive to nostalgic middle-class Americas. Your videos take what'd otherwise be gibberish and make it wholly understandable... in less than ten minutes! Very few people have such skill for brevity and efficiency. I give you an A+.

    Currently writing a speech to present to my entire High school about Quantum Mechanics and the Development of it over time, aswell as its use in the Real world, and also explaining Quantum Computers. These Videos have helped a lot, since this is a pretty big deal

    What did you mean by
    ""Anneal the initial hamiltonian"
    And how do we know what biases and couples to chose?

    what do you mean by ""rump down the initial hamiltonian??

    The shapes looks like 4d tetrahedron also, the energy state movement/graph convey that, they can't reach the forth line plus it only moves forward in time, is that the case or can it move backwards ?

    What do you think of the solution they discovered in Australia where they'll be using light particles (photons) to act as gates? -- The Fredkin Gate I believe it was called?

    Awesome explanation!

    So to me it sounded like the Hamiltonian aspect is about economy of motion and the Eigenspectrum sorts possible mapped solutions to best solve a problem logistically. Like the traveling salesman problem?

    Thanks for the videos! I was wondering if this Hamiltonian actually describes the energy of the D-Wave hardware, or does the D-Wave just try to minimise the energy of this Hamiltonian - and the Hamiltonian has no relation to the energy of the hardware?

    Great video! Does anybody recommend any resources that contain a more technical explanation of quantum annealing? Thank you.

    what is it about the problem that specifies the width of the gap?

    Your video is very informative! I would like to ask your permission to share the videos to the other website in China for the embarrassing reason that UA-cam is blocked from accessing in China. I'll translate them into Chinese, and I'll give the sources of the original website. Thank you so much!

    something I haven't heard yet is why is the lowest energy state the answer for a problem verses the high energy state?

    • @rudirs3
      @rudirs3 8 років тому

      +Billy Guy States naturally want to be low energy, so the problem is arranged so the solution will be the lowest energy.

    is this real. I just heard about it, and I've finished some decent research on it. I do not know if this is actually working. the dwave 2x is the third one made. so if it does work, how well?

    brilliant, personally I prefer quantum annealing computing, I think this is stable computer.

    How is the entanglement setup in the system. If each spin is stored inside a SQUID , how do you couple SQUIDS to each other.

    • @michaelcharlesthearchangel
      @michaelcharlesthearchangel 7 років тому

      I use hyperPunctuation markers,
      aside from applying standard hyperGrammatics for a generAl quantum language\code,
      for design(at)ing and interCoupling the entanglement states/periods of so called "SQID"s 2gether.
      Like the chronotopic, code theoretic interaction marker ":.:" ("interaction") for indicating a sheer synchronic modus (ponens or tollens or politens or otherwise) of an empiric and thus observable/measurable relationship.

      (At the same time) We realize that a quantum world demands a quantum language.

    annealing doesn't inherit any of the quantum mechanics nature like superposition instead it's like simulating a system that actually works like a quantum computer

    okay I am not very smart I'm just a dumb hillbilly but correct me or validate me here please? initially what they're trying to do is solve the problem as subtle as possible without it having to drastic of effect on the Mass meaning the people? Visa Vie a Mandela effect with as little backlash as notice or possible? but the unyielding law seems to be that no matter what lowest Energy Solution you go to there's always going to be someone or something that will not agree with it? like the original copy is never truly erased? help me out here guys thank you

      Mystery of existence? The answer: two After 3 months of your comment not getting answered, i think it's safe to say : NOBODY KNOWS WHAT THE FUCK IS GOING ON HERE. (takes bow) Thank you, thank you

    what you say it does not make, it is just mythology. Initial and final hamiltonian, it does not make sense. A Hamiltonian is just one.

    Hamiltonian? And you guys are physicists?? Using a word like "Hamiltonian"??? -Maybe you guys should run for office instead of talking rubbish!
