Automatic ensemble teleportation even under sub-optimal conditions — •Thomas Krüger — Theoretische Physik, Fakultät für Naturwissenschaften, Universität Paderborn, Warburger Str. 100, 33098 Paderborn

The possibility of teleportation is surely the most interesting consequence of quantum non-separability. So far, however, teleportation schemes have been formulated by use of state vectors and considering individual entities only. In the present contribution the feasibility of teleportation is examined on the basis of the rigorous ensemble interpretation of quantum mechanics (not to be confused with a mere treatment of noisy EPR pairs) leading to results which are unexpected from the usual point of view. Emphasis is laid on realistic situations where mixed and/or semi-separable states come into play.
