The invention discloses a remote teleportation method based on a four-bit Cluster state. For network terminal users Alice and Bob, through help of an intermediate node, communication between a networkterminal Alice and the other terminal user Bob is completed. The method comprises the four steps that 1, the four-bit most entangled Cluster state is shared by the terminal users Alice, Bob and the intermediate node Li (i=1, 2, 3, ..., p), and a quantum entanglement channel of the terminal users Alice and Bob and the intermediate node Li (i=1, 2, 3, ..., p) is built; 2, modulation and measurementare conducted, wherein CZ operation is conducted on corresponding particles by the terminal user Alice and the intermediate node Li, moreover, Bell measurement is conducted on the particles in handsby the intermediate node, and measurement results are announced; 3, a direct quantum channel between the terminal user Alice/Bob and the other terminal user Bob/Alice is built according to the Bell measurement results of the intermediate node through unitary operation; 4, according to difference of information transferring modes, the terminal users Alice and Bob choose corresponding restoring operation according to the Bell measurement results of each other to achieve intercommunication.
