Wigner-function description of quantum teleportation in arbitrary dimensions and a continuous limit
Mátyás Koniorczyk, Vladimír Bužek, József Janszky · Physical Review A · 2001
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.
