  • An excellent summary of the field of quantum computing. Find out more about Qiskit at qiskit.org and their RUclips channel / qiskit
    And get the poster here: store.dftba.com/collections/d...
    With this video I aim to give a really good overview of the field of quantum computing with a clear explanation of how they work, why people are excited about quantum algorithms and their value, the potential applications of quantum computers including quantum simulation, artificial intelligence and more, and the different models and physical implementations people are using to build quantum computers like superconducting devices, quantum dots, trapped ions, photons or neutral atoms, and the challenges they face.

    A short 'war story': I spent 17 years in supercomputer field (Cray Research, Thinking Machines, etc.). In 1992 I completed a project to mathematically construct the first N elements in the periodic table from first principles (using Feynman-Kac integrals while accounting for spin). I used the 65,000 CPU Connection Machine (27 Gflops, $18 million). I was able to compute the ground energy state atomic structure up through boron (N = 5), within 16 hours. Today, researchers may be able to reach N = 30. It is clear the only way we will be able to simulate molecular biology is with quantum computers!

      We're already making breakthroughs with classical computers and have incredible potential with neural networks....but if we could use a quantum computer to model the system? Just program the energy function and get out the lowest energy state solutions? That would be the silver bullet. The golden ticket to understanding all of biology, even the entirety of cells at the atomic level.

    @alvinwu8509 Год назад +2

    Just recently read a book about chaos theory and it talked about weather forecasting - specifically, how difficult it is to accurately predict the weather beyond a few days. This boils down to how complex systems such as weather are self referential and as such even the smallest changes in one of its parameters will eventually lead to a massive change down the line. We are talking about how even a millionth decimal place in the speed of wind could eventually lead to massive changes down the line and this change is not linear in fashion. I think that's where quantum computers could be quite useful as we can model the entire ranges of a parameter using qubits rather than trying millions of combinations for a slight change in just one parameter.

      The language of quantum is linear algebra so I’d start there if you don’t already know a bit of it. You can then go on to learn about quantum states, and operators on those states like the Pauli matrices and different operators composed of the Pauli matrices like the Hadamard gate. Then I’d say start with Deutsch’s Algorithm and Grovers algorithm. Quskit and IBM actually have awesome resources for learning all this, and IBM’s circuit composer is super cool to play around with too. If you aren’t too interested in the physics of it all the textbook Quantum Computing for computer scientists is pretty good, although it skips over a lot of the physics that, until better error corrected computers are available, is really valuable to know.

    You have a knack for explaining complicated things clearly. This was helpful for me. I’m an EE and programmer and have the goal of learning how to program quantum computers. I’ve been using qisqit to learn about quantum gates, but it is taking forever because I’m really trying to understand each step I take thoroughly - because I know what’s coming, a point at which I will say “the universe cannot possibly work like that”. In fact, my goal is to prove to myself that it DOES work that way, by accomplishing something with a quantum computer that clearly demonstrates its quantum weirdness.
    You mentioned that a classical computer can be made from just nor gates and bits, but of course bits can be made from nor gates.

    Very well explained Dominic, thank you. This helped a lot in furthering my understanding in quantum computing. I see you quickly touched on it but AI seems like a great application for QC's. In a recent video Veritasium touched on how analog computers are somewhat more effective and efficient at computing neural algorithms (simulations) than classical computers but it seems to me that quantum computers would be even better. Don't ask me how exactly because I just don't know but crunching vast amounts of data seems to be a QC's bread and butter. This is all big brain stuff for someone who is used to binary!

      These then get "translated" to the basis vector components (uppon wave function collapse) which we call "classical" states. Its also worth mentioning that the classical state basis components arent classical at all and are also uncertain according to the uncertainty principle. The classical states we call "normal" reality are just an infenetesimally tiny fraction of all the available states. The uncertainty principle isnt weird, our states are.

      ​@@immko I enjoy doing it it's not my job or anything but I am good at certain things and I enjoy teaching other people what I have learned and enjoy doing. I makes me happy to see them ''get it''. I might have gotten better at it over the years by practicing.
      I somewhat agree with you, I think that a lot of things can be thought and learned, with practice even perfected. But there is a limit to that, a simple example would be Francis Nganou, the current UFC heavy weight champion. He has been training for ONLY 5 years, he has what they call ''the touch of death''. If he connects he will knock you out.
      Power punching is one of those things you can''t teach. Any person can learn to punch harder but no matter how hard and how long you train you will never be able to generate as much power as him.
      I think the same applies to mental feats as well. You can get better at mathematics and physics but no matter how much you practice you will never be as creative and smart as Einstein or Newton.
      We can always improve but we are limited by our genes and the environment that molded the expression of those genes.

    • @immko

      @@noisemagician That's where our opinions seems to differ. On Francis I agree completely, it comes from genes and if you don't have them there is nothing we can do, at least before crispr gets better or something similar.
      I do disagree on the mental side of it, I really believe nobody is born with 200 IQ, they have to learn it. Information is only patterns and if you train your pattern recognition and creativity you can understand anything that our brains can comprehend. There are some limitations that science seems to have discovered, for example some people can at a glance memorize 3 things where others can go up to 5 or even 6 in very rare cases, but it's not clear how it helps or if there is downsides on other areas.
      Learning mental capabilities are still not easy and 'gift' could be described as "started very early in life and had enough luck to do it effectively" which would result in many years of effective training without knowing its training.
