【 摘 要 】

A scheme for the multihop non-destructive teleportation of an arbitrary single-qudit state based on various non-maximally entangled Greenberger–Horne–Zeilinger channels is proposed here. The parallel entanglement swap is used to form a direct d -dimensional ( d ≥ 2 ) entangled channel shared between the sender and the receiver. The authors’ propose a novel idea that the third-party Charlie with high quantum information processing technology executes the channel modulation, which reduces the technical requirements of the sender and the receiver. In addition, if the teleportation fails, the unknown state will be restored by the sender. This work provides a feasible method for teleportation and ensures the integrity of the unknown quantum information.
