We can't, at least not with Turing machines or with things equivalent to Turing machines. Feynman showed in 1982 [1] that Turing machines suffer exponential slowdowns when trying to simulate quantum physics.
Computing physical processes beyond some special cases (which include many very useful physical processes) will have to wait for advances in quantum computing.
