It is possible to predict the future state of a system in QM from the initial state. QM equations are parabolic/hyperbolic and so from a global initial state one can deduce both future and past. What one cannot do is to deduce the future or past of a local patch based on the state of that local patch at a particular moment in time. The QM state is global and there is no way to isolate the local patch from influence of arbitrary far away points.
