Genuine tripartite entanglement of W state subject to Hawking effect of a Schwarzschild black hole
Shu-Min Wu, Xiao-Wei Fan, Xiao-Li Huang +1
We study the genuine tripartite entanglement (GTE), one-tangle and two-tangle of W state of fermionic fields in the background of a Schwarzschild black hole. We find that, with the…

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),…
