Nonlocal coherence harvesting from quantum vacuum
Rui-Di Wang, Shu-Min Wu, Xiao-Li Huang
It is well known that nonlocal coherence reflects nonclassical correlations better than quantum entanglement. Here, we analyze nonlocal coherence harvesting from the quantum vacuum…

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 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…
