A note on entanglement detection via the generalized realignment moments
Xiaofen Huang, Xishun Zhu, Bin Chen +2
The experimental detection of quantum entanglement is of great importance in quantum information processing. We present two separability criteria based on the generalized realignme…
Trade-off relations and enhancement protocol of quantum battery capacities in multipartite systems
Yiding Wang, Xiaofen Huang, Shao-Ming Fei +1
First, we investigate the trade-off relations of quantum battery capacities in two-qubit system. We find that the sum of subsystem battery capacity is governed by the total system…
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…
Classical representation of local Clifford operators
Cai-Hong Wang, Jiang-Tao Yuan, Zhi-Hao Ma +2
It is known that every (single-qudit) Clifford operator maps the full set of generalized Pauli matrices (GPMs) to itself under unitary conjugation, which is an important quantum op…
Improving Quantum Battery Capacity in Tripartite Quantum Systems by Local Projective Measurements
Yiding Wang, Hui Liu, Shao-Ming Fei +1
The impact of local von Neumann measurements on quantum battery capacity is investigated in tripartite quantum systems. Two measurement-based protocols are proposed and the concept…
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…
