The problem here is the way you think a quantum computer must be used. Clearly, you are wired on the factorization problem: here we start with all possible combinations and at the end only one is selected. Furthermore, the entire computation is collapsed to the classical domain (if there was no collapse, we would have at least two states: the "answer state" and the empty one). Here, in the Universe simulation, no classical collapse is intended, the "result" remains in the quantum state as said before (it may be linked to another computation round ). So there is not a single word selected, what remains is a set of words, each one is an elementary cube address., precisely the addresses in the "on" state. >Or, to be precise, because the time dimension is to be eliminated, >(you're looking at "all time") : how can a number of 813 bits >tell me which of 10^183 (~2^608) cubes are in the "on" state ???? If the matter density in the simulation is defined so that here are 2^608 cubes in the "on" state, then the simulation starts with 2^813 states and end with 2^608. If you wan you can use a second computation step and reduce this to a single state, in classical space, that second round describes a big crunch where the universe is compressed into a single point in space and time. Once more, I must stress this is not the normal fate of a simulation.
