How does quantum computing work?

  1. Jul 4, 2013 #1
    how is it that we are able to get atoms to work like bits? and what is their counting system? because simply counting in 1's and 0's doesnt seem to make so much sense when electrons can be doing any number of things when they are not being observed.

    i recently watched this


    but it didnt explain things as much as i would like it to.

    such as having 2 "qubits" is equivalent to 4 bits. can anyone explain? thank you

    I thought quantum computers did not use 0's and 1's?
