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…
