In this paper we propose two schemes for teleportation of a sub-class oftripartite states, the first one with the four-qubit cluster state and thesecond one with two Bell pairs as entanglement channels. A four-qubit jointmeasurement in the first case and two Bell measurements in the second areperformed by the sender. Appropriate unitary operations on the qubits at thereceiver's end along with an ancilla qubit result in the perfect teleportationof the tripartite state. Analysis of the quantum circuits employed in theseschemes reveal that in our technique the desired quantum tasks are achievedwith lesser quantum cost, gate count and classical communication bits comparedwith other similar schemes.
