量子認知脳科学 図

Just as quantum mechanics has described a microscopic world, there is growing interest in the possibility that the mathematical framework of quantum mechanics can explain the liquidity of human thought. This has been proposed as “quantum cognition”, which can be expected as a new framework for the phenomena that have been treated as irrationality of human thought in cognitive science. Brain activities that produce thoughts are also understood as classical physical phenomena so far, but if the “superposition” state of the mind and the “quantum entanglement” state can be explained by the mathematical model of quantum mechanics, there may be days when the quantum cognitive state is proved by the brain function.
