Is the Brain a Quantum Computer?

Some physicists propose that the brain acts
like a quantum computer (a machine that uses quantum physics
laws to work). The main proponents of this this are physicist
Roger Penrose and anesthesiologist Stuart Hamerhof. Penrose's
argument rests on the idea that humans are able to solve
problems that computer algorithms are not, therefor human
brain's cannot be compared to a regular computer and must rely
on quantum mechanics. He uses the argument that because
human's are able of knowing the truth of Godel's Unprovable
statements (a theory is either false and provable or true but
unprovable), the human conscious and thought is
non-computable. He says that though a formal proof system
can't prove it's own inconsistency, human mathematicians can
prove Godel's unprovable statements therefore human brains
aren't running on a computable algorithm (i.e. a quantum
level)
Hammerhof suggested that micro-tubules in the brain would be
capable of quantum computations. Together Penrose and Hamerhof
developed the Orch OR model (Orchestrated Objective Reduction
model).
