Skew information-based uncertainty relations for quantum channels
The most general quantum measurements in quantum mechanics are described by quantum channels (quantum operations), and intrinsic uncertainties emerge from the state–channel interaction. In this paper, we study...

Quantum criticality from Fisher information
Quantum phase transition is primarily characterized by a qualitative sudden change in the ground state of a quantum system when an external or internal parameter of the Hamiltonian is continuously varied. Inve...

Evaluating the geometric measure of quantum discord
We derive analytic formulas for the geometric measure of quantum discord introduced by Dakic, Vedral, and Brukner for pure states and (2×n)-dimensional states and establish a general lower bound for arbitrary sta...
