Wave-particle-mixedness redistribution in Schwarzschild spacetime
Sumeng Wang, Xiaofen Huang
The redistribution of the wave feature, particle feature, and mixedness is investigated for two-qubit isotropic states in Schwarzschild spacetime under Hawking radiation and enviro…
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…
Quantum correlations of tripartite mixed states in the black hole quantum atmosphere
Anqi Zhang, Yanze Zheng, Xiaofen Huang +1
The paper studies how Hawking radiation near a black hole affects the entanglement and nonlocality of a three‑partite mixed quantum state, showing that these quantum correlations p…
Noise is not always detrimental: the capacity of quantum batteries is enhanced in black holes
Xukun Wang, Xiaofen Huang, Zhihao Ma +2
Quantum battery capacity, as a critical metric for quantifying energy storage and release in quantum systems, exhibits complex behaviors in curved spacetime and noisy environments.…
Gaussian quantum steering of coupled three-mode squeezed vacuum in an expanding universe
Guang-Wei Mi, Xiaofen Huang, Tinggui Zhang
The coupled three-mode squeezed vacuum is a representative multimode squeezed Gaussian state featuring unique steerability. This work investigates Gaussian quantum steering distrib…
