No, quantum computers of modest size can simulate quantum systems of modest size. So maybe, maybe you could simulate a classical version of the universe (of course there is no such thing) but you can't get most of the answers out (you only get to measure once). To simulate a universe of qubits, you need a universe of qubits. Or more time. What you can get rid of is the exponential slowdown, which is huge.
