Causal-diamond thermalization induces nonseparability in N-partite quantum systems
Hui-Chen Yang, Shu-Min Wu
We investigate the nonseparability of multipartite bosonic and fermionic and states in a causal diamond spacetime using the Abe-Rajagopal (AR) -conditional entropy. Th…
Topology-dependent relativistic degradation of multipartite entanglement
Shu-Min Wu, Si-Han Shang, Xu Han +2
The influence of relativistic motion on quantum entanglement is commonly attributed to acceleration-induced thermal noise. Here we show that, for asymmetric multipartite states, th…
Asymmetric quantum steering harvested near a Lorentz-violating BTZ black hole
Si-Yu Liu, Xin-Ze Song, Xiang-Yue Yu +3
We investigate the harvesting of quantum steering and its directional asymmetry between two Unruh-DeWitt detectors in a Lorentz-violating BTZ black hole spacetime. Since the detect…
Bosonic and fermionic mutual information of N-partite systems in dilaton black hole background
Xiao-Wei Teng, Rui-Yang Xu, Hui-Chen Yang +1
We investigate multipartite total amount of correlations by analyzing the mutual information of N-partite states for both free bosonic and fermionic fields in the background of a G…
Non-monotonic evolution of multipartite entanglement under the Unruh effect
Shu-Min Wu, Si-Han Shang, Si-Yu Liu +3
We investigate the behavior of tetrapartite entanglement in a four-qubit Dicke state under relativistic motion by employing the Unruh-DeWitt detector model, where one detector unde…
Does relativistic motion really freeze initially maximal entanglement?
Si-Han Li, Hui-Chen Yang, Rui-Yang Xu +1
We investigate the relativistic dynamics of quantum entanglement in a four-qubit cluster () state using a fully operational Unruh-DeWitt detector framework. Contrary to the w…
