Are there techniques for ternary photonic computer ?

  1. Oct 9, 2016 #1
    If instead of electrons, which are spin 1/2 particles, we could use photons, which are spin 1, could we use this fact to have a three valued logic (1,0,-1) ?

    How to store photons like in an electronic computer to build the memory ? Are there techniques that allow that ? Thanks.

    the spin value of electrons has NOTHING to do with how they are used in computers.

    What have you ever heard that led you to believe otherwise?

    Sorry I was already in the future, when quantum computers will exist. But in theory ?

    A photon has only two spin states. (And if you want to know why, you should ask in the proper section)
