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 …

Genuine tripartite nonlocality and entanglement in curved spacetime

SM Wu, HS Zeng - The European Physical Journal C, 2022 - Springer
We study the genuine tripartite nonlocality (GTN) and the genuine tripartite entanglement
(GTE) of Dirac fields in the background of a Schwarzschild black hole. We find that the …

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 …

The noncommutative quantum Hall effect with anomalous magnetic moment in three different relativistic scenarios

RRS Oliveira, G Alencar, RR Landim - General Relativity and Gravitation, 2023 - Springer
In the present paper, we investigate the bound-state solutions of the noncommutative
quantum Hall effect with anomalous magnetic moment in three different relativistic …

Irreversible degradation of quantum coherence under relativistic motion

J Wang, Z Tian, J Jing, H Fan - Physical Review A, 2016 - APS
We study the dynamics of quantum coherence under Unruh thermal noise and seek under
which condition the coherence can be frozen in a relativistic setting. We find that the frozen …

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 …

Relativistic quantum information and time machines

TC Ralph, TG Downes - Contemporary Physics, 2012 - Taylor & Francis
Relativistic quantum information combines the informational approach to understanding and
using quantum mechanical systems–quantum information–with the relativistic view of the …

Does anti-Unruh effect assist quantum entanglement and coherence?

SM Wu, XW Teng, JX Li, HS Zeng, T Liu - New Journal of Physics, 2024 - iopscience.iop.org
In this paper, we use the concepts of quantum entanglement and coherence to analyze the
Unruh and anti-Unruh effects based on the model of Unruh–DeWitt detector. For the first …

Entangled detectors nonperturbatively harvest mutual information

K Gallock-Yoshimura, RB Mann - Physical Review D, 2021 - APS
We investigate how entangled inertial Unruh-DeWitt detectors are affected by interaction
with a quantum field using a nonperturbative method. Inertial detectors in a (3+ 1) …

Unruh effect for detectors in superposition of accelerations

LC Barbado, E Castro-Ruiz, L Apadula, Č Brukner - Physical Review D, 2020 - APS
The Unruh effect is the phenomenon that accelerated observers detect particles even when
inertial observers experience the vacuum state. In particular, uniformly accelerated …
