I'm not sure that there's consensus among neuroscientists and electrical engineers and what-have-yous (who are presumably the people doing the project) that the influence of quantum effects would be any more significant than they are in a field effect transistor. Of course, the project could prove them wrong, but what a remarkable result that would be, to falsify a significant hypothesis with your first attempt.
