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 …

Unveiling quantum entanglement degradation near a Schwarzschild black hole

E Martín-Martínez, LJ Garay, J León - Physical Review D—Particles, Fields …, 2010 - APS
We analyze the entanglement degradation provoked by the Hawking effect in a bipartite
system Alice-Rob when Rob is in the proximities of a Schwarzschild black hole while Alice is …

Cavity Heisenberg-spin-chain quantum battery

FQ Dou, H Zhou, JA Sun - Physical Review A, 2022 - APS
We propose a cavity Heisenberg-spin-chain (CHS) quantum battery (QB) with the long-
range interactions and investigate its charging process. The performance of the CHS QB is …

Entanglement of Dirac fields in an expanding spacetime

I Fuentes, RB Mann, E Martin-Martinez, S Moradi - Physical Review D …, 2010 - APS
We study the entanglement generated between Dirac modes in a 2-dimensional conformally
flat Robertson-Walker universe. We find radical qualitative differences between the bosonic …

Multipartite entanglement of fermionic systems in noninertial frames

J Wang, J Jing - 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 …

Entanglement dynamics for uniformly accelerated two-level atoms

J Hu, H Yu - Physical Review A, 2015 - APS
We study, in the paradigm of open quantum systems, the entanglement dynamics of two
uniformly accelerated atoms with the same acceleration perpendicular to the separation …

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

J Wang, J Deng, J Jing - 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 …

Redistribution of particle and antiparticle entanglement in noninertial frames

E Martín-Martínez, I Fuentes - Physical Review A—Atomic, Molecular, and …, 2011 - APS
We analyze the entanglement tradeoff between particle and antiparticle modes of a Dirac
field from the perspective of inertial and uniformly accelerated observers. Our results show …

Sudden death of entanglement and teleportation fidelity loss via the Unruh effect

AGS Landulfo, GEA Matsas - Physical Review A—Atomic, Molecular, and …, 2009 - APS
We use the Unruh effect to investigate how the teleportation of quantum states is affected
when one of the entangled qubits used in the process is under the influence of some …
