Multi-hop nondestructive teleportation independent of channel parameters

In this paper, we present a multi-hop nondestructive teleportation scheme independent of channel parameters based on Bell pairs, where the coefficients of the quantum channel are unknown for all the communication nodes. With Bell measurement and channel matching technology, the unknown channel parameters can be eliminated probabilistically with the help of the intermediate nodes. Then the source node Alice can teleport an unknown state to the remote destination node Bob. Our scheme firstly generalizes the teleportation to the scenario of independent of channel parameters, which makes the requirement of quantum channel reduced. Our scheme preserves the initial unknown state even if this teleportation fails. Moreover, performance analysis shows that our scheme has a higher communication efficiency.
