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…
Correlations Between Quantum Battery Capacity and Quantum Resources for Two-qubit System
Yiding Wang, Xiaofen Huang, Tinggui Zhang
We investigate the relationship between quantum battery capacity and quantum resources in a two-qubit system consisting of mutually coupled battery and charger subsystems. We find…
Dynamics of Entanglement in Schwarzschild Black Holes
Fang Xie, Ying Yang, Tinggui Zhang +1
To characterize the effect of Hawking radiation induced by the quantum atmosphere beyond the event horizon on entanglement, we employ concurrence as the entanglement measure for a…
Quantum discord of mixed states under noisy channels in the curved spacetime
Yuxuan Xiong, Zhiling Pi, Tinggui Zhang +1
We focus our attention on two-qubit mixed states as initial states, and apply the geometric measure of quantum discord to investigate quantum discord properties in the background o…
