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),…

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…
