    Watching in 2019. I’d like to reassure my fellow commenters from 2015: in 2019 we still have no idea about what quantum computer is. We actually have to rely on 4 years old videos trying to explain us what this is about, but still no joy.

    I dont understand what exactly the computer is detecting. A normal computer detects the presence of electrons to flip a switch. A quantum computer is detecting the spin of an atom? or its polarity? and what atom is it detecting? I assume the particle has to be a special kind that can 'exist in multiple states simultaneously', so what particles are quantum computers using, and why are they in a state of multiple existences

    If quantum entanglement can send information regardless of distance does that mean you could send information faster than the speed of light? Imagine the possibilities if you want kurzgesgat to make a video on quantum entanglement communication like

      Of course its going to seem like its instantaneous i mean...

    • Matea Cannavino

      There's a theory that during entanglement the quantum atoms become one, and reactions are simultaneous.

      +King Taco according to the laws of physics nothing can be processed or can travel faster than the speed of light as beyond that point there is an abyss of nothingness, at least of what we know, considering science hasn't really defined "nothing" yet.

      Basically 1's and 0's act like on and off switches for traveling electrons yadda yadda yadda.... Can be put into groups such as AND, OR, NOT, NAND, which basically dictates whether a bunch of 1's and 0's become a 1 or 0 blah blah ... Quantum stuff appears. Now on and off become angry modern feminist and saying stuff like gender is fluid until looked at...
