Abstract: (560 Views) |
The multihop teleportation is a useful scheme for quantum teleportation in long-distance, that there is no direct entanglement between a source node and a destination node. In this paper, multihop teleportation of single-qubit, two-qubit, and N-qubit states are presented by using the composition of the GHZ state and EPR state as a shared quantum channel between two adjacent nodes. In this scheme, the source node and intermediate nodes can make measurements simultaneously and send the measurement results to the destination node in parallelism, so that the transmission speed increases compared with the hop-by-hop transmission. Finally, the efficiency of this method is calculated. This scheme is suitable for transferring information in communication networks.
