    You know why NASA has interest on that?: "Quantum Computers" feed a lot of power just for the cooling (almost sub Zero to activate super-conductivity) but outer-Space's temperature is roughly 2.7 Kelvin and it's more efficient to run it in the ISS than here on Earth.
    It's not about the possible development of "Quantum Entanglement" long distance communication thinggy.

    Our current computer cannot compute Quantum mechanics simply because of the "errors in our Math", most of the units aren't exactly accurate. That's why simple units became expanded into sophisticated formulas while it can be simplified if someone out there can discover the "simpliest" units out there (ex. dalton:Mass ;Kelvin:Temp).

    Is it possible to purposefully exploit the flaws in transistors that are sub 14 microns if they were arranged in a tight grid? In other words, if I had a grid of transistors that were so small they shared electrons as a signal passed through - could we get a visual representation of the wave form function by setting everything to 0 and updating one transistor?

    Out of all your videos, this is the single one that explains the subject very poorly. You explain what is super position but not how that enables representing more data with fewer bits; the fact that 4 qbits can be in a superposition of all 16 states is irrelevant as that basically means they do not represent ANY info, same way as if you were asked whether you're hungry, then answering "yes and no" doesn't give any info.

    I would caution strongly against comparing computers and brains as identical. There's plenty of reason to believe that computation alone is not enough to display the kinds of complex phenomenon associated with invention, inductive reasoning, and originating technologies through commutative language (Mathematics) that must be of an order of magnitude greater than the subsystems we develop into machine technology.

    7 nm is becoming the norm in a few years. 3 nm is possible at the moment but it's not profitable to make. Some phones even have 7nm already!
    In 5 years, once 3nm is the norm, everyone will push for 1nm.

    I always wondered if quantum entaglement could be used to send data near instantly across any distance.
    For example, a super computer with entangled output qubits linked to input qubits in another computer the entire world away. If the output is measured to be 1 (or forced to be 1) then the input the world away would be 0, and so information can be shared across the world by encoding info in the output computer in opposite to the computers actual computational result.
    The application here, besides data transfer without lag, is that super computers could be built on distant planets or orbiting stars, magnificent in scale and power, and the info could be read by a much smaller computer on our planet.
    But then, I'm no quantum scientist and my knowledge of the subject is fairly limited, I just wondered if it was a possibility. Is there a limit in physical distance of two quantum entagled qubits, and can we force a qubit to always give us the desired unit we would like?

      They also work the other way. It could be the case that quantum encryption is literally impossible to hack (like, according to the laws of physics impossible, not just "we don't have a good enough computer" impossible).

    The transistors are not 14 nanometers or what ever number of nanometers. What that number means is the smallest part of the transistor. Don't get me wrong the transistors are tiny but not that size.
    Quantum computers will never be commerical for consumers not maybe. They might not even be commercial useable.
    The thing is there are many different ways for quantum computers to work there have been a best one figured out yet and no standards.
    While transistors might be at size limit there are many other technology as you see multiple cores prob will have photonic computers so optical fibers instead of copper circuits and wires.

      It is German & idiomatically translates to "in a nutshell".
      Literally, it's a compound word of "kurz" & "sagen". "Kurz" means "short", whereas "sagen" is the verb "to say", with the prefix "ge" being the German past tense marker... so literally, it might translate to something like "briefly said".
