Abstract We investigate the criteria for two-qubit states that could be transmitted via W-state. The appropriate criterias are entangled states which have maximum number of terms equal to number of channel terms and maximum of two different constants. We have also shown quantum teleportation of a particular type of two-qubit state via three-qubit GHZ-like states, with Alice possesses the first qubit of the channel and the rest belongs to Bob. GHZ-like state is an entangled state which has different characteristic from GHZ state. It is stronger against particle loss than GHZ state. Furthermore, GHZ-like states which can teleport a particular type of two-qubit state are GHZ-like states which have two terms.
