Content: However, Penrose argues that such Turing machines (and thus any computer) have certain limitations which he doesn't believe the brain necessarily has. Quantum Indeterminacy
Some proponents of quantum consciousness have put forth the idea that quantum indeterminacy—the fact that a quantum system can never predict an outcome with certainty, but only as a probability from among the various possible states—would mean that quantum consciousness resolves the problem of whether or not humans actually have free will. So the argument goes, if human consciousness is governed by quantum physical processes, then it is not deterministic, and humans, therefore, have free will. There are a number of problems with this, which are summed up by neuroscientist Sam Harris in his short book "Free Will," where he stated: "If determinism is true, the future is set—and this includes all our future states of mind and our subsequent behavior. And to the extent that the law of cause and effect is subject to indeterminism—quantum or otherwise—we can take no credit for what happens. There is no combination of these truths that seems compatible with the popular notion of free will. The Double-Slit Experiment
One of the best-known cases of quantum indeterminacy is the quantum double slit experiment, in which quantum theory says that there is no way to predict with certainty which slit a given particle is going to go through unless someone actually makes an observation of it going through the slit. However, there is nothing about this choice of making this measurement which determines which slit the particle will go through. In the basic configuration of this experiment, there is a 50 percent chance the particle will go through either slit, and if someone is observing the slits, then the experimental results will match that distribution randomly.
