Characterizing local unitary equivalence of multipartite states by local unitary Bargmann invariants
Yi Shen, Lin Chen, Shao-Ming Fei
Local unitary (LU) equivalent states are crucial for understanding the structure of quantum entanglement. We investigate the LU equivalence based on the LU Bargmann invariants (LUB…
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.…
Simultaneous Detection of High-Dimensional Entanglement for Two Unknown Quantum States
Mao-Sheng Li, Chang-Yue Zhang, Zheng Zheng +7
The state overlap, quantified via $\tr[ρσ]$, is a metric widely used to assess the closeness between two quantum states and . Although global state overlap alone does not di…
Machine learning-aided direct estimation of coherence and entanglement for unknown states
Ting Lin, Zhihua Chen, Kai Wu +3
Quantum coherence and entanglement are fundamental resources in quantum technologies, yet their efficient estimation for unknown states by employing minimal resources in experiment…
