摘　　要：General conditions are given in order to perform a perfect teleportation process in the case where the Hilbert spaces involved have different dimensions. An explicit expression is obtained for the quantum channel associated with the standard teleportation protocol T<SUB>0</SUB> with an arbitrary mixed state resource. The transmission fidelity of the corresponding quantum channel is given.
