Do gravitational waves assist the genuine tripartite entanglement harvesting?
Xiang-Yue Yu, Xiao-Li Huang, Shu-Min Wu
We investigate the harvesting of genuine tripartite entanglement by three linearly arranged Unruh-DeWitt detectors locally coupled to a massless scalar field in a gravitational wav…
Dilaton gravity can enhance quantum coherence and reduce entanglement
Zejun Wang, Zhihong Liu, Yu-Xuan Wang +1
We investigate the influence of the Garfinkle-Horowitz-Strominger (GHS) dilaton black hole on different quantum resources of Dirac fields beyond the single-mode approximation. By e…
Asymmetric quantum steering harvested near a Lorentz-violating BTZ black hole
Si-Yu Liu, Xin-Ze Song, Xiang-Yue Yu +3
We investigate the harvesting of quantum steering and its directional asymmetry between two Unruh-DeWitt detectors in a Lorentz-violating BTZ black hole spacetime. Since the detect…
Non-monotonic evolution of multipartite entanglement under the Unruh effect
Shu-Min Wu, Si-Han Shang, Si-Yu Liu +3
We investigate the behavior of tetrapartite entanglement in a four-qubit Dicke state under relativistic motion by employing the Unruh-DeWitt detector model, where one detector unde…
Does gravitational wave assist vacuum steering and Bell nonlocality?
Shu-Min Wu, Rui-Di Wang, Xiao-Li Huang +1
We study quantum steering and Bell nonlocality harvested by the local interaction of two Unruh-DeWitt detectors with the vacuum massless scalar field, both in the presence of gravi…
Genuine N-partite entanglement in Schwarzschild-de Sitter black hole spacetime
Shu-Min Wu, Xiao-Wei Teng, Xiao-Li Huang +1
Complex quantum information tasks in a gravitational background require multipartite entanglement for effective processing. Therefore, it is necessary to investigate the properties…
Curvature-enhanced multipartite coherence in the multiverse
Shu-Min Wu, Chun-Xu Wang, Rui-Di Wang +3
Here, we study quantum coherence of N-partite GHZ (Greenberger-Horne-Zeilinger) and W states in the multiverse consisting of N causally disconnected de Sitter spaces. Interestingly…
Does Hawking effect always degrade fidelity of quantum teleportation in Schwarzschild spacetime?
Shu-Min Wu, Xiao-Wei Fan, Rui-Di Wang +3
Previous studies have shown that the Hawking effect always destroys quantum correlations and the fidelity of quantum teleportation in the Schwarzschild black hole. Here, we investi…
Would quantum coherence be increased by curvature effect in de Sitter space?
Shu-Min Wu, Chun-Xu Wang, Dan-Dan Liu +2
We study the quantum coherence in de Sitter space for the bipartite system of Alice and Bob who initially share an entangled state between the two modes of a free massive scalar fi…
