But then you have the problem of whether "observers" simulated by a quantum computer can actually make measurements. The essence of a measurement is the formation of permanent records in the environment. Quantum computers cannot do this unless they stop and print out a result. Your quantum computer simulation requires a redefinition of the concept of measurement so that it becomes essentially meaningless.
