Quantum discord of Ganssian states in an expanding universe
Siwei Li, Xiaofen Huang
We investigate the redistribution of continuous-variable quantum discord within the framework of an expanding universe. We find that quantum discord exhibits stronger sensitivity t…

Geometric quantum discord in the black hole quantum atmosphere
Siwei Li, Xiaofen Huang
We investigate the geometric quantum discord of bipartite Werner states influenced by Hawking radiation in the quantum atmosphere of a Schwarzschild black hole. We find that the ge…
