Teleportation with an Arbitrary Mixed Resource as a Trace-Preserving Quantum Channel
Sergio A Albeverio, Shao-Ming Fei, Wenli Yang · Communications in Theoretical Physics · 2002
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 0 with an arbitrary mixed state resource. The transmission fidelity of the corresponding quantum channel is given.
