There's something interesting called the no-cloning theorem (http://en.wikipedia.org/wiki/No-cloning_theorem http://en.wikipedia.org/wiki/No-cloning_theorem). Basically, it says it is impossible to copy an unknown quantum state. This could have implications on "copying" vs "moving" human identity (whatever that is) around.
