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…
Tripartite quantum steering in Schwarzschild spacetime
Guang-Wei Mi, Xiaofen Huang, Tinggui Zhang
We investigate the effects of Hawking radiation on quantum steering and steering asymmetry in a tripartite system embedded in Schwarzschild spacetime. All tripartite steering types…
Quantumness near the Schwarzschild black hole based on W-state
Guang-Wei Mi, Xiaofen Huang, Shao-Ming Fei +1
We investigate certain quantumness in the vicinity of the Schwarzschild black hole by utilizing the W state. We explore the influence of the Hawking effect on the l_1-norm of quant…
Genuine four-partite Bell nonlocality in the curved spacetime
Guang-Wei Mi, Xiaofen Huang, Shao-Ming Fei +1
The quantum Bell nonlocality plays a crucial role in quantum information processing. In this paper, we first obtain the quantitative analytical expression of the genuine four-parti…
Impact of the Hawking Effect on the Fully Entangled Fraction of Three-qubit States in Schwarzschild Spacetime
Guang-Wei Mi, Xiaofen Huang, Shao-Ming Fei +1
Wu et al. [J. High Energ. Phys. 2023, 232 (2023)] first found that the fidelity of quantum teleportation with a bipartite entangled resource state, completely determined by the ful…
