Concentration Effect of Quantum and Classical Correlations during Quantum Brachistochrone Evolution

We explore the role of quantum brachistochrone evolution to quantum and classical correlations in three-qubit systems, and show that the time-averaged correlations of three-qubit systems exhibit an obvious concentration effect, which means both the standard deviations of time-averaged quantum and classical correlations decrease with the separation angle. Furthermore, we find that the concentration effect on genuine tripartite entanglement is the most significant during the quantum brachistochrone evolution of three-qubit systems.
