Wigner-function description of quantum teleportation in arbitrary dimensions and continuous limit

Abstract

We present a unified approach to quantum teleportation in arbitrary dimensions based on the Wigner-function formalism. This approach provides us with a clear picture of all manipulations performed in the teleportation protocol. In addition within the framework of the Wigner-function formalism all the imperfections of the manipulations can be easily taken into account.Comment: 8 pages, LaTeX, 1 figure (included).
