Before revision: There is a widespread view that the human brain is so complex that it cannot be efficiently simulated by universal Turing machines , let alone ordinary classical computers . During the last decades the question has therefore been raised whether we need to consider quantum effects to explain the imagined cognitive power of a conscious mind.
