Entanglement degradation of static black holes in effective quantum gravity
Xiaobao Liu, Wentao Liu, Shu-Min Wu
Quantum information science has been broadly explored in Einstein gravity and in various modified gravity theories; however, its extension to quantum gravity settings remains large…

Does the survival and sudden death of quadripartite steering in curved spacetime truly depend on multi-directionality?
Xiaobao Liu, Wentao Liu, Si-Han Shang +1
We systematically investigate the directional dependence of Gaussian quadripartite quantum steering and its redistribution among different modes in the background of a Schwarzschil…

Entangled Unruh-DeWitt detectors amplify quantum coherence
Shu-Min Wu, Yu-Xuan Wang, Wentao Liu
We explore the quantum coherence between a pair of entangled Unruh-DeWitt detectors, interacting with a quantum field, using a nonperturbative approach in a (3+1)-dimensional Minko…
