Suppose our universe is actually a wave function evolving in a computer in another universe acoording to the standard linear wave equations. If there is a way to send a signal to the administrator of this computer, how many bits of information would we need to send in order for him to be able to find us in the wave function?

My impression (please correct me if I'm wrong) is that this would be a very large number, much larger than the number of bits needed to completely describe a human brain. If this is true, then in what sense does quantum mechanics offer an explaination for our perceptions of the world (i.e. the inside view in Max Tegmark's terminology)? It seems like a complete explaination would be longer than the data itself. By complete explaination I mean boundary conditions of the wave function, the wave equations, and the information needed to extract the inside view that we're seeing from the wave function.
