Probabilistic Quantum Teleportation of Four-particle Cluster State

Abstract

In this paper, four non-maximal Bell states are used as quantum channel to complete the probabilistic teleportation of four-particle cluster states. In the process, four Bell measurements are performed by the sender. Then a local Pauli operation is executed by the receiver according to the sender’s measurement results. An auxiliary qubit is introduced and a special unitary transformation is implemented. Finally the probabilistic teleportation can be achieved by the receiver after measurement on the auxiliary qubit.
