Not ever. If FTL information transfer is invented, it will not be via quantum teleportation. See http://en.wikipedia.org/wiki/No-communication_theorem for why. There are some interesting things you can do with quantum mechanics with regard to cryptography, though. I don't think FTL information transfer is possible, though, because Einstein's theories of relativity have been experimentally verified to a great degree, and they show that if signals could propagate faster than light, you could easily create some serious causality violations. As much as I like time travel stories, I just don't think physics works that way. --Levi /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
