We study the dynamics of classical correlation, quantum discord, and measurement-induced disturbance of Dirac fields in the background of a dilaton black hole. We present an alternative physical interpretation of single mode approximation for Dirac fields in black hole spacetimes. We show that the classical and quantum correlations are degraded as the increase of black hole's dilaton. We find that, comparing to the inertial systems, the quantum correlation measured by the one-side measuring…

Quantum Correlation and Coherence in the Background of Dilaton Black Hole
We study quantum correlation and coherence of Dirac fields in the background of a dilaton black hole. It is found that there exists quantum correlation and coherence transfer between particle and
Probing quantum entanglement in the Schwarzschild space-time beyond the single-mode approximation
In this paper, we deduce the vacuum structure for Dirac fields in the background of Schwarzschild space-time beyond the single-mode approximation and discuss the performance of quantum entanglement
Inevitable degradation and inconsistency of quantum coherence in a curved space-time
TLDR
Based on dynamic analyses on bipartition system, the frozen conditions and the inconsistency of quantum coherence are investigated and it is concluded that this inconsistency is an intrinsic trait of coherence in the curved space-time.
Quantum steering and its asymmetry of open quantum systems in accelerated frames
We study the dynamics of quantum steering between two-mode Dirac fields in the non-inertial frame and interact with two independent thermal baths. Special attention is paid to the distinction of the
Quantum coherence of fermionic systems in noninertial frames beyond the single-mode approximation
In this paper, we investigate the behavior of the quantum coherence for bipartite fermionic systems in noninertial frames beyond the single-mode approximation. It is shown a redistribution of
Quantum coherence behaviors of fermionic system in non-inertial frame
TLDR
The results show that this quantifiers in two region converge at infinite acceleration limit, which implies that this measures become independent of Unruh modes beyond the single-mode approximations.
