Why? You postulate physicalism. Show me your theory of mind, please. By UDA it cannot be computationalist. With comp it can be argued that the constraining factors are only logico-arithmetical. The SWE should be emerging. We must explain why quantum computation described by "e^iH" seems, from the point of view of the observer, to supersede classical computation described by "H". Bruno
