Afaik man-caused quantum tunneling is at its infancy, with only particles moved/tunnelled. Assuming that at some future time it becomes possible to teleport a human (a vast collection of linked particles) would the entity teleported really be the human or just a copy which to others will be impossible to differentiate from the original human? Iirc the teleportation of a particle destroys the original (? Or at least makes it disappear) so wouldnt the original human die? Which wont matter to others, but if you die when teleported it means you wont be in the copy at all.
