Does anti-Unruh effect assist quantum entanglement and coherence?
Shu-Min Wu, Xiao-Wei Teng, Jin-Xuan Li +2
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 time…
Genuinely accessible and inaccessible entanglement in Schwarzschild black hole
Shu-Min Wu, Xiao-Wei Teng, Jin-Xuan Li +3
The genuine entanglement of Dirac fields for an N-partite system is investigated in Schwarzschild spacetime and the analysis is carried out using the single-mode approximation. Due…
Fermionic steering is not nonlocal in the background of dilaton black hole
Shu-Min Wu, Jin-Xuan Li, Xiao-Ying Jiang +3
We study the redistribution of the fermionic steering and the relation among fermionic Bell nonlocality, steering, and entanglement in the background of the Garfinkle-Horowitz-Stro…
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…
Gaussian quantum steering in multi-event horizon spacetime
Shu-Min Wu, Jin-Xuan Li, Xiao-Wei Fan +3
We study Gaussian quantum steering in the Schwarzschild-de Sitter (SdS) spacetime that is endowed with both a black hole event horizon (BEH) and a cosmological event horizon (CEH),…
