| In recent years, Quantum teleportation has become the hot issue of research, which is the important part of quantum information and quantum computation. Quantum teleportation has developed rapidly after the iconic article proposed by Bennett et al. More and more people start studying the quantum teleportation, therefore, kinds of protocols appear constantly, which can transport one and more particles, of which channels can be constructed by EPR state, multiparticle entanglement and cluster state, etc. Some of these schemes have been demonstrated experimentally. The theoretical and experimental achievements indicate that the era of quantum information is coming.Because of external disturbance, the maximum entanglement cannot exist for a long time. So the research about the non-maximum quantum channel is meaningful. In most schemes about probabilistic teleportation of quantum states using a partially entangled state as a quantum channel, the receiver not only must introduce an auxiliary particle and make a corresponding unitary transformation to reconstruct the original quantum state, but also needs to fully know the information of the non-maximally entangled state. Evidently, the previous schemes are not valid on condition that the receiver has not total knowledge of the partially entangled state. In order to expend applied range, we study of quantum teleportation when the information of the partially entangled state is only available for the sender.In this paper, the quantum teleportation when only the sender knows the channel’s information is realized using three qubits entanglement GHZ state and W state as the quantum channel respectively, then the effect of entanglement parameter error on probability and fidelity of teleportation is studied. At last, we discuss the application of our protocols and make the conclusion of this paper, which provides the beneficial reference for the construction of multiple quantum communication network. |
