Quantum coherence and geometric quantum discord

ML Hu, X Hu, J Wang, Y Peng, YR Zhang, H Fan - Physics Reports, 2018 - Elsevier
Quantum coherence and quantum correlations are of fundamental and practical significance
for the development of quantum mechanics. They are also cornerstones of quantum …

Unruh effect in quantum information beyond the single-mode approximation

DE Bruschi, J Louko, E Martín-Martínez, A Dragan… - Physical Review A …, 2010 - APS
We address the validity of the single-mode approximation that is commonly invoked in the
analysis of entanglement in noninertial frames and in other relativistic quantum-information …

Observer-dependent entanglement

PM Alsing, I Fuentes - Classical and Quantum Gravity, 2012 - iopscience.iop.org
Understanding the observer-dependent nature of quantum entanglement has been a central
question in relativistic quantum information. In this paper, we will review key results on …

Quantum Fisher information in noninertial frames

Y Yao, X **ao, L Ge, X Wang, C Sun - Physical Review A, 2014 - APS
We investigate the performance of quantum Fisher information (QFI) under the Unruh-
Hawking effect, where one of the observers (eg, Rob) is uniformly accelerated with respect …

Multipartite entanglement of fermionic systems in noninertial frames

J Wang, J **g - Physical Review A—Atomic, Molecular, and Optical …, 2011 - APS
The bipartite and tripartite entanglement of a 3-qubit fermionic system when one or two
subsystems accelerate are investigated. It is shown that all the one-tangles decrease as the …

Genuine multipartite concurrence for entanglement of Dirac fields in noninertial frames

WC Qiang, GH Sun, Q Dong, SH Dong - Physical Review A, 2018 - APS
We apply genuine multipartite entanglement concurrence to investigate entanglement
properties of Dirac fields in noninertial frames. We present analytical concurrences for …

Classical correlation and quantum discord sharing of Dirac fields in noninertial frames

J Wang, J Deng, J **g - Physical Review A—Atomic, Molecular, and Optical …, 2010 - APS
The classical and quantum correlation sharing between modes of Dirac fields in the
noninertial frame are investigated. It is shown that (i) the classical correlation for the Dirac …

Bosonic and fermionic coherence of N-partite states in the background of a dilaton black hole

WM Li, SM Wu - Journal of High Energy Physics, 2024 - Springer
A bstract We study the N-partite coherences of GHZ and W states for free bosonic and
fermionic fields when any n observers hover near the event horizon of a Garfinkle-Horowitz …

Basis-independent quantum coherence and its distribution under relativistic motion

MM Du, HW Li, Z Tao, ST Shen, XJ Yan, XY Li… - The European Physical …, 2024 - Springer
Recent studies have increasingly focused on the effect of relativistic motion on quantum
coherence. Prior research predominantly examined the influence of relative motion on basis …

Quantum properties of fermionic fields in multi-event horizon spacetime

Q Liu, SM Wu, C Wen, J Wang - Science China Physics, Mechanics & …, 2023 - Springer
We investigated the properties of quantum entanglement and mutual information in the multi-
event horizon Schwarzschild-de Sitter (SdS) spacetime for massless Dirac fields. For the first …
