Abstract
There are no ``unknown quantum states.'' It's a contradiction in terms. Moreover, Alice and Bob are only inanimate objects. They know nothing. What is teleported instantaneously from one system (Alice) to another system (Bob) is the applicability of the preparer's knowledge to the state of a particular qubit in these systems. The operation necessitates dual classical and quantum channels. Other examples of dual transmission, including ``unspeakable information,'' will be presented and discussed. This article also includes a narrative of how I remember that quantum teleportation was conceived.
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…
