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…
Simultaneous measurements on cosmic curvature and opacity using latest HII regions and observations
Ying Yang, Tonghua Liu, Jiayuan Huang +3
The different spatial curvatures of the universe affect the measurement of cosmological distances, which may also contribute to explaining the observed dimming of type Ia supernova…
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…
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…

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…
