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 …

Genuine N-partite entanglement and distributed relationships in the background of dilation black holes

SM Wu, YT Cai, WJ Peng, HS Zeng - The European Physical Journal C, 2022 - Springer
With the complexity of information tasks, the bipartite and tripartite entanglement can no
longer meet our needs, and we need more entangled particles to process relativistic …

Quantum Fisher information in noninertial frames

Y Yao, X Xiao, 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 …

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 …

Quantum coherence and distribution of N-partite bosonic fields in noninertial frame

SM Wu, HS Zeng, HM Cao - Classical and Quantum Gravity, 2021 - iopscience.iop.org
We study the quantum coherence and its distribution of N-partite GHZ and W states of
bosonic fields in the noninertial frames with arbitrary number of acceleration observers. We …

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 …

Schwarzschild spacetime and the analysis is carried out using the single-mode …

Fate of entanglement between two Unruh-DeWitt detectors due to their motion and background temperature

P Chowdhury, BR Majhi - Journal of High Energy Physics, 2022 - Springer
A bstract We investigate the fate of initial entanglement between two accelerated detectors
