Steered quantum coherence and quantum Fisher information in spin-chain system

In this paper, we investigate steered quantum coherence, i.e., the l1 norm of steered coherence and the relative entropy of steered coherence, and the quantum Fisher information in the Gibbs state of two-qubit XXZ systems. Their variations with respect to the temperature, external magnetic field, an...

Summary:In this paper, we investigate steered quantum coherence, i.e., the l1 norm of steered coherence and the relative entropy of steered coherence, and the quantum Fisher information in the Gibbs state of two-qubit XXZ systems. Their variations with respect to the temperature, external magnetic field, and interaction intensities are analyzed both analytically and numerically in detail. The similar behaviors among these three quantum measures in the XXZ model are presented.
