Quantum discord of Gaussian states in non-inertial frames
Siwei Li, Xiaofen Huang
We investigate the redistribution of continuous-variable Gaussian quantum discord under the Unruh effect for both one and two uniformly accelerated observers. The discord shared be…

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…
