Phase damping destroys quantum Fisher information of W states
(Elsevier Science BV, 2014-09-05)
We study the quantum Fisher information (QFI) of W states in the basic decoherence channels. We show that, as decoherence starts and increases, under i) depolarizing, QFI smoothly decays; ii) amplitude damping, QFI first ...
