Abstract

It has been considered that a maximal entangled state is needed for complete quantum teleportation. However, Kossakowski and Ohya proposed a scheme of complete teleportation for nonmaximal entangled state [1]. Basing on their scheme, we proposed a teleportation model of 2‐level state with a non‐maximal entangled state [2]. In the present study, we construct its expanded model, in which Alice can teleport m‐level state even if non‐maximal entangled state is used.
