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…
Entanglement degradation of static black holes in effective quantum gravity
Xiaobao Liu, Wentao Liu, Shu-Min Wu
Quantum information science has been broadly explored in Einstein gravity and in various modified gravity theories; however, its extension to quantum gravity settings remains large…
Does the survival and sudden death of quadripartite steering in curved spacetime truly depend on multi-directionality?
Xiaobao Liu, Wentao Liu, Si-Han Shang +1
We systematically investigate the directional dependence of Gaussian quadripartite quantum steering and its redistribution among different modes in the background of a Schwarzschil…
Entangled Unruh-DeWitt detectors amplify quantum coherence
Shu-Min Wu, Yu-Xuan Wang, Wentao Liu
We explore the quantum coherence between a pair of entangled Unruh-DeWitt detectors, interacting with a quantum field, using a nonperturbative approach in a (3+1)-dimensional Minko…
Does acceleration always degrade quantum entanglement for tetrapartite Unruh-DeWitt detectors?
Si-Han Li, Si-Han Shang, Shu-Min Wu
Previous studies have shown that the Unruh effect completely destroys quantum entanglement and coherence of bipartite states, as modeled by entangled Unruh-DeWitt detectors. But do…
Quantum steering for different types of Bell-like states in gravitational background
Si-Han Li, Si-Han Shang, Shu-Min Wu
In a relativistic framework, it is generally accepted that quantum steering of maximally entangled states provide greater advantages in practical applications compared to non-maxim…
Do maximally entangled states always have an advantage over non-maximally entangled states in Schwarzschild black hole?
Shu-Min Wu, Si-Han Li
It is generally believed that quantum entanglement in the maximally entangled states is greater than quantum entanglement in the non-maximally entangled states under a relativistic…
