Generating multi-atom entangled W states via light-matter interface based fusion mechanism
(Nature Publishing Group, 2015-11-09)W state is a key resource in quantum communication. Fusion technology has been proven to be a good candidate for preparing a large-size W state from two or more small-size W states in linear optical system. It is of great ... -
Parameter estimation with Dzyaloshinskii–Moriya interaction under external magnetic fields
(Springer, 2020-02-01)We study the effects of external magnetic fields on the precision of parameter estimation with thermal entanglement of two spins in XX model, in the presence of Dzyaloshinskii–Moriya (DM) interaction. Although DM interaction ... -
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 ...
