    Distillability sudden death and sudden birth in a two-qutrit system under decoherence at finite temperature

    Distillability sudden death and sudden birth in a two-qutrit system locally subject to amplitude dam** channel at a finite temperature have been studied in detail. By using the negativity and the realignment...

    Generation and protection of steady-state quantum correlations due to quantum channels with memory

    We have proposed a scheme of the generation and preservation of two-qubit steady-state quantum correlations through quantum channels where successive uses of the channels are correlated. Different types of noi...

    Enhancing parameter estimation precision by non-Hermitian operator process

    Recently, Zhong et al. (Phys Rev A 87:022337, 2013) investigated the dynamics of quantum Fisher information (QFI) in the presence of decoherence. We here reform their results and propose two schemes to enhance an...
