Could an n-qbit quantum computer somehow emulate a >n-qbit quantum computer? And if so, wouldn't that "emulation" run exactly as if it was real? Could we make an arbitrarily large q.c. that way... a whole artificial universe a la H2G2?

I don't know nearly enough about quantum computation to know if this makes sense or not... just tossing a message in a bottle into this Sea of Infinity.

This idea came to me in a dream last night... based on the idea that the universe consists of a very small number of things (maybe 2, maybe just 1... or... 0?) on the fundamental level... but that there is the emulation (or illusion) of infinite numbers of things.
