Abstract
Recently, a new class of W-states has been defined by Agarwal and Pati (Phys. Rev. A 74:062320, 2006) and it has been shown that they can be used as a quantum channel for teleportation and superdense coding. In this work, we identify those three-qubit states from the set of the new class of W-states which are most efficient or suitable for quantum teleportation. We show that with some probability \(|W_{1}\rangle=\frac{1}{2}(|100\rangle+|010\rangle+\sqrt{2}|001\rangle)\) is best suited for teleportation channel in the sense that it does not depend on the input state.
