Abstract

We propose a method to realize the teleportation of an unknown entangledstate that consists of many qudits through a partially entangled-quditquantum channel with the help of 2log2d-bit classicalcommunication. The operations used in the teleportation process includea generalized Bell-state measurement and a series of single-quditπ-measurements performed by Alice, a series of generalizedqudit-Pauli gates and two-level unitary gates, as well as a qubitmeasurement performed by Bob. For a maximally entangled quantum channel,the successful probability of the teleportation becomes unit.
