This doubling of the absolute measure is important. In another posting you
wrote about being teleported to many places and then being annihilated
everywhere except at the original place. This won't affect the probability
of being alive at the original place. But in a QC experiment where you have
many outcomes, all leading to death except one, the probability of
experiencing that branch is very small.
