Complete freezing of initially maximal entanglement in Schwarzschild black hole
Si-Han Li, Hui-Chen Yang, Rui-Yang Xu +1
Gravitational effects associated with black holes are widely believed to universally degrade quantum entanglement, with the loss of maximal entanglement being particularly severe a…

Does relativistic motion really freeze initially maximal entanglement?
Si-Han Li, Hui-Chen Yang, Rui-Yang Xu +1
We investigate the relativistic dynamics of quantum entanglement in a four-qubit cluster () state using a fully operational Unruh-DeWitt detector framework. Contrary to the w…

Can Hawking effect of multipartite state protect quantum resources in Schwarzschild black hole?
Shu-Min Wu, Xiao-Wei Teng, Hui-Chen Yang +3
Most previous studies on relativistic quantum information have primarily focused on the vacuum state and the first excited state in two-mode entangled syste…
