    "abstract": "True tripartite entanglement of the state of a system of three qubits can be\nclassified on the basis of stochastic local operations and classical\ncommunications (SLOCC). Such states can be classified in two categories: GHZ\nstates and W-states. It is known that GHZ states can be used for teleportation\nand superdense coding, but the prototype W-state cannot be. However, we show\nthat there is a class of W-states that can be used for perfect teleportation\nand superdense coding.",
