I'm pretty sure quantum mechanics already forgoes conventional causality. Attosecond interactions take place in such narrow slices of time that the uncertainty principle turns everything into a blur where events can't be described linearly. In other words, the math sometimes requires that effect precedes cause. As far as we can tell, causality and conservation of energy is only preserved on a macroscopic scale. (IANAQP, but I'm going off my recollections of books by people who are.)
