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 …

Entanglement has been studied extensively for unveiling the mysteries of non-classical
correlations between quantum systems. In the bipartite case, there are well known measures …

We estimate the initial weight and phase parameters $(\theta,\phi) $ of a single qubit system
initially prepared in the coherent state $\renewcommand {\ket}[1]{\bigl\vert# 1\bigr\rangle}\ket …

The quantum Fisher information of an atomic system interacting with a single cavity mode in
the presence of Kerr medium is discussed. It is shown that quantum Fisher information for an …

We study the quantum Fisher information (QFI) per particle of an open (particles can enter
and leave the system) and dissipative (far from thermodynamical equilibrium) steady state …

We study the quantum Fisher information (QFI) of W states and W-like states under
decoherence. In particular, we find that on the contrary to amplitude damping and …

Quantum entanglement is at the heart of quantum information processing. Ordering the
quantum systems due to their entanglement is a popular problem of the field. For two level …

We study the quantum Fisher information (QFI) of a system of several particles which is in a
superposition of a GHZ and two W states with arbitrary relative phase. We show that as the …

Recent studies on quantum Fisher information (QFI) have been focused mostly on qubit
systems within the context of how entanglement helps surpassing the classical limit of …

We have investigated the teleportation of quantum Fisher information (QFI) for a single-qubit
system by using two different maximally entangled pure states as resources influenced by a …
