Abstract:We propose and analyze a quantum synchronization sharing scheme among the nodes of a star-type quantum network. Utilizing dark state resonances, we show the biggish differences between two subsystems can be corrected by magnified effective coupling although each subsystem is of relative weak coupling intensity and high dissipation effects. Moreover, we elucidate that the quantum synchronization contains available classical and quantum correlations simultaneously. In particular, synchronization measure shows high consistency with quantum concurrence for qubit system, which means it possesses nonlocality and can ensure the advantage of quantum information processing. Finally, a brief discussion about parameter selection is given so that our scheme can be applied expediently in relevant experiments. (C) 2016 Elsevier B.V. All rights reserved.
