摘要：
Teleportation of a qutrit state with two different non-maximally entangled qutrit states as quantum channels linking three nodes of an intending quantum network is studied via an ancilla method. With this method a global accumulation approach (GAA) different from the usual node progression approach (NPA) is proposed. Comparisons between two approaches from the four aspects of quantum resource consumption, operation complexity, success probability and efficiency indicate that the GAA is much better than the NPA overall. The average fidelities in both methods are calculated and compared, it is shown that the average fidelity in the GAA is higher than that in the NPA. The error self-correction in the GAA is confirmed and its efficiency relative to the channel-state coefficients is explicitly given.
