[QUOTE="freyar, post: 6662017, member: 40227"] Right! But, if it worked, you would get a perfect recreation of yourself at the moment you started the process. Almost. The way quantum teleportation works --- at least for single particles, which is all we know how to do --- is more like you prepare two entangled boxes, and you keep one and put one of them on the plane. Then, when it arrives, you entangle yourself with the box you kept. This effectively destroys you at your first location but creates you at the second location (not quite simultaneously, since the origin teleporter would have to send some information to the destination). The practical upshot is that you could create many pairs of these "entangled boxes" and ship one half of each pair to various destinations, so you could really set up a quantum teleportation business. The other thing about the quantum aspect of this is that if you could really do it (though I think practically it'd be pretty much impossible), the "copy" would be quantum mechanically indistinguishable from the original. In other words, you wouldn't really be "killing" the original since a set of indistinguishable particles would take on the exact same quantum state. What look like the nearly insurmountable problems, though, are (1) keeping the two "entangled boxes" actually entangled over macroscopic times and distances and (2) figuring out how to do quantum processes to something as big as a person. Of course, these are related issues. [/QUOTE]
