| Abstract: | The states of triqubit systems have an important category W states. A class of asymmetric W states |W n 〉123 were proposed by Agrawal and Pati (Phys Rev A 74:062320, 2006). We introduce an entangled system composed of the |W n 〉123 states and Bell pairs and show its utility for perfect teleportation and superdense coding. |
