Witnessing criticality in non-Hermitian systems via entropic uncertainty relation
youneng Guo, Guoyou Wang
Non-Hermitian systems with exceptional points lead to many intriguing phenomena due to the coalescence of both eigenvalues and corresponding eigenvectors, in comparison to Hermitia…
Entropic uncertainty relation under quantum channels with memory
Youneng Guo, Maofa Fang, Ke Zeng
Recently, Xu et al. [Phys. Rev. A 86, 012113(2012)] explored the behavior of the entropic uncertainty relation under the influence of local unital and nonunital noisy channels for…
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…
Pairwise quantum discord for a symmetric multi-qubit system in different types of noisy channels
You-neng Guo, Mao-fa Fang, Zeng Ke +1
We study the pairwise quantum discord (QD) for a symmetric multi-qubit system in different types of noisy channels, such as phase-flip, amplitude damping, phase-damping, and depola…
Correlation quantum beats induced by non-Markovian effect
Hao-Sheng Zeng, Yan-Ping Zheng, Ning Tang +1
For two qubits independently coupled to their respective structured reservoirs (Lorentzian spectrum), quantum beats for entanglement and discord are found which are the result of q…
Equivalence of the measures of non-Markovianty for open two-level systems
Hao-Sheng Zeng, Ning Tang, Yan-Ping Zheng +1
In order to depict the deviation of quantum time evolution in open systems from Markovian processes, different measures have been presented. We demonstrate that the measure propose…
