Quantum teleportation (tunnelling) involves the ability of an electron to transport from one position to another without evidence of traversing the intervening space. This is only possible in quantum physics (due to the plausibility of another dimension which is not amenable to our current measurement techniques). This allows chirality which is the ability of a chemical substance to assume “form stereotaxis” (folding) within the same molecular formula. To be stable, the form must possess the lowest energy minima. Such quantum chirality effects also occur in very negligible(instantaneous) time. Such effects open up shortcuts to many different, otherwise inaccessible states and the such availability of low energy states is taken advantage of and routinized by biological evolution (cf. enzyme mediated catalysis1).
Dopamine is responsible for pleasure, physical movement, motivation, learning etc. Such a versatility of diverse functions (for dopamine) is (possibly) feasible with the tunneling/chirality effects of quantum computation2. Such substance economy for functional utility is the essence of stochaistic evolution and is available with most neurotransmitters. It is also possible that the exact temporal effect (of dopamine) may be determined by the “fixity of the mental state” required (or measured) at a particular time (cf. Schrödinger’s cat, states of being dead or alive).
Evolution, by employing quantum knowledge has perhaps molded the nervous systems to be capable of amplifying internal quantum effects upwards; and thus evade mechanical determinism. Consider the dopamine molecule. For dopamine to function properly in a requisite circumstance, the molecule must fold up on itself in the right way near its absolute energy minimum to achieve the most highly functional configuration for the required circumstance. The linear sequence of the amine (“primary structure”) does not provide the blueprint for the correct usable conformation of the sequence of folds (final “tertiary structure”). Dopamine must therefore assume a several number of (functional) conformational states with a large number of relative energy minima. This can be achieved by annealing (cf. artificial neural networks, cellular automata, spin glass mapping) to their minimum energy in an instantaneous time frame with negligible energy expenditure. Such may be the marvel of quantum physics that is employed by evolution to achieve its objective.
