Sudden change of local quantum uncertainty and geometry for arbitrary two-qubit X-states

Autor: Guo-you Wang, Hu-ping Peng, Ke Zeng, You-neng Guo

Publikováno v: Quantum Information Processing. 19

Local quantum uncertainty (LQU) as a reliable measure of nonclassical correlations has been recently proposed by Girolami et al. (Phys Rev Lett 110:240402, 2013). In this paper, we have derived an explicit analytical expression of LQU and presented t

The Influences of Quantum Coherence on the Positive Work and the Efficiency of Quantum Heat Engine with Working Substance of Two-Qubit Heisenberg XXX Model

Autor: Hu-Ping Peng, Hong-Mei Zou, Min Yu, Mao-Fa Fang

Publikováno v: International Journal of Theoretical Physics. 57:1872-1880

We study the influences of quantum coherence on the positive work and the efficiency of quantum heat engine (QHE) based on working substance of two-qubit Heisenberg model under a constant external magnetic field. By using analytical and numerical sol

Local quantum uncertainty in a two-qubit Heisenberg spin chain with intrinsic decoherence

Autor: Ying Chen, Qing-long Tian, You-neng Guo, Hu-ping Peng, Zhi-guang Tan

Publikováno v: Physica Scripta. 96:075101

Quantum correlation plays an important role in quantum information processing, for which various quantifiers have been proposed so far. In this paper, we address the dynamics of local quantum uncertainty (LQU) as a reliable quantifier of quantum corr
