Imprecise quantum steering inequalities in tripartite systems
Yan Zhao, Li-Juan Li, Zheng-Peng Xu +2
Quantum steering, as a manifestation of nonlocal quantum correlations, plays a crucial role in enabling various quantum information processing tasks. However, practical implementat…
Entanglement and entropy uncertainty in black hole quantum atmosphere
Shuai Zhang, Li-Juan Li, Xue-Ke Song +2
In this work, we investigate the properties of Hawking radiation induced by the quantum atmosphere beyond the event horizon, by considering two detectors in Schwarzschild spacetime…
Quantumness and entropic uncertainty for a pair of static Unruh-DeWitt detectors
Yu-Kun Zhang, Tariq Aziz, Li-Juan Li +3
In this study, we investigate a pair of detectors operating in Minkowski space-time and analyze the characteristics of various quantum resources within this framework. Specifically…
Quantifying Quantumness in (A)dS spacetimes with Unruh-DeWitt Detector
Li-Juan Li, Xue-Ke Song, Liu Ye +1
Probing quantumness in curved spacetime is regarded as one of fundamental and important topics in the framework of relativistic quantum information. In this work, we focus on the t…
Entropic uncertainty and quantum non-classicality of Unruh-Dewitt detectors in relativity
Yu-Kun Zhang, Li-Juan Li, Xue-Ke Song +2
An object moving with the acceleration will change the temperature of environment around it, because of the presence of the Unruh thermal effect. In this work, we investigate the i…
Quantifying genuine tripartite entanglement by reshaping the state
Dong-Dong Dong, Li-Juan Li, Xue-Ke Song +2
Although genuine multipartite entanglement (GME), as one quantum resource, is indispensable in quantum information processing, most of the existing measures cannot detect GME faith…
