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...
