    "abstract": "Teleportation for pure states, mixed states with standard and optimal\nprotocols are introduced and investigated systematically. An explicit equation\ngoverning the teleportation of finite dimensional quantum pure states by a\ngenerally given non-local entangled state is presented. For the teleportation\nof a mixed state with an arbitrary mixed state resource, an explicit expression\nis obtained for the quantum channel associated with the standard teleportation\nprotocol. The corresponding transmission fidelity is calculated. It is shown\nthat the standard teleportation protocol is not optimal. The optimal quantum\nteleportation is further studied, its fidelity is given and shown to be related\nto the fully entangled fraction of the quantum resource, rather than the single\nfraction as in the standard teleportation protocol.",
