Optimal distillation of three-qubit W states
Published 19 Jul 2010 in quant-ph, math-ph, and math.MP | (1007.3171v1)
Abstract: Some of the asymmetric three qubit $W$ states are used for perfect teleportation, superdense coding and quantum information splitting. We present the protocols for the optimal distillation of the asymmetric as well as the symmetric $W$ states from a single copy of any three qubit $W$ class pure state.
