The Ergotropy of Quantum Batteries under Unruh Effect
Yiding Wang, Shengyan Ma, Xiaofen Huang +1
We study the effects of uniform acceleration on the ergotropy of quantum batteries modeled as Unruh-DeWitt detectors, in both bipartite and tripartite setups. In the bipartite syst…
Quantum correlations of tripartite mixed states in the black hole quantum atmosphere
Anqi Zhang, Yanze Zheng, Xiaofen Huang +1
We investigate quantum state texture, genuine multipartite entanglement, and tripartite nonlocality of a tripartite mixed state in the black hole quantum atmosphere. By introducing…
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…
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.…
