Are brains quantum computers?

  1. Aug 2, 2013 #1
    I've heard it claimed before that brains could be quantum computers (I think it was on Through the Wormhole). Is there any evidence of this?

    I'm thinking about reading up on quantum computation, but don't know anything about quantum mechanics yet. I'm mostly interested in machine learning, and not yet sure if quantum computing is a worthwhile thing to study. I.e. I'm not sure if quantum computers are possible/practical. If brains are quantum computers, then I would at least know quantum computing is possible and practical in some sense.

    No; the theory was made popular by a theoretical physicist (Penrose). It's not accepted by mainstream neuroscientists.

    Quantum mind theories have been widely criticised and if they ever meet a burden of proof they can be discussed. Right now though they are not appropriate for this forum.
