Replica? What about relocating the original from one place to another?
How do they know that it wasn't C teleported to A in an almost magical reversal of time?
If you can replicate the quantum numbers of a particle, it is indistinguishable from the original.
As far as the universe can tell, it is the same thing!
in the teleportation of star trek, mr spock always reasoned that he never existed after teleportation, but was a mere replica of himself...
