A scheme for probabilistic teleportation of an unknown two-particle entangled state via a four-qubit non-maximally entangled cluster state as quantum channel is proposed. In this scheme,the unknown entangled states can be teleported with a certain probability,which is determined by the smallest two of the coefficients' absolute values of the cluster state. What's more,if quantum channel is maximally entangled cluster state,the probabilistic teleportation becomes usual teleportation.

We propose a novel scheme to probabilistically teleport an unknown two-level quantum state when the information of the partially entangled state is only available for the sender. This is in contrast with the fact that the receiver must know the non-maximally entangled state in previous typical schemes for the teleportation. Additionally, we illustrate two potential applications of the novel scheme for probabilistic teleportation from a sender to a receiver with the help of an assistant, who plays distinct roles under different communication conditions, and our results show that the novel proposal could enlarge the applied range of probabilistic teleportation.
