Asher Peres, one of the coinventors of teleportation, had an amusing story (with a serious subtext) about the question of what is teleported: "Later, when a newsman asked me whether it was possible to teleport not only the body but also the soul, I answered “only the soul.” Even that is a gross oversimplification."

In teleportation experiments to date only some degrees of freedom are teleported. So it doesn't usually make a whole lot of sense to say "the atom" was teleported. Rather, it'll just be the quantum state associated to nuclear spin states, or electronic degrees of freedom, or whatever.

I also wonder if it gets exponentially harder to transmit larger and larger quantum states (the only reason I posit this is because it always seems like Nature prohibits us from doing all kinds of cool things in an exponentially hard way).
