Protecting coherence in the non-Hermitian two-level system
Wei-Chen Wang, Mao-Fa Fang
We have constructed a non-Hermitian two-level system (a PT -symmetric system) in dissipative environments, and investigated the quantum coherence in the non-Hermitian two-level sys…
Non-Hermitian-assisted enhancement precision of parameter estimation
Youneng Guo, Maofa Fang, Gouyou Wang +2
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 an…
Protecting and enhancing spin squeezing under decoherence using weak measurement
Xiang-Ping Liao, Man-Sheng Rong, Mao-Fa Fang
We propose an efficient method to protect spin squeezing under the action of amplitude-damping, depolarizing and phase-damping channels based on measurement reversal from weak meas…
Generation and protection of steady-state quantum correlations due to quantum channels with memory
You-neng Guo, Mao-fa Fang, Guo-you Wang +1
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 corre…
