Directional effects of the Unruh effect on steering harvesting
Shu-Min Wu, Rui-Yang Xu, Zhihong Liu
We investigate directional quantum steering harvesting by two uniformly accelerated non-identical Unruh-DeWitt detectors coupled to a massless scalar field in the Minkowski vacuum.…
Nonlocal correlation in quantum network under relativistic motion
Si-Han Li, Tian-Yang Wang, Ai-Yan Tong +1
We investigate the relativistic dynamics of network nonlocality in general -local networks with chain and star topologies using the Unruh-DeWitt detector model. We show that the…
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…
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…
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…
Complete freezing of initially maximal entanglement in Schwarzschild black hole
Si-Han Li, Hui-Chen Yang, Rui-Yang Xu +1
Gravitational effects associated with black holes are widely believed to universally degrade quantum entanglement, with the loss of maximal entanglement being particularly severe a…
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…
