As far as I am aware, it only requires a probabilistic Turing machine, which is the same as a normal Turing machine (or a quantum computer) in terms of what it can compute.
Ultra precise simulation like that isn't in any case necessary, after all humans can create humans without needing 40 digit decimal places. Or create cars or computers etc without simulating everything down to each electron.
