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…
Reflecting boundary induced modulation of tripartite coherence harvesting
Shu-Min Wu, Xiao-Ying Jiang, Xiang-Yue Yu +2
We study the extraction of quantum coherence by three static Unruh-DeWitt (UDW) detectors that interact locally with a massless scalar vacuum field in the vicinity of an infinite p…
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…
Can boundary configuration be tuned to optimize directional quantum steering harvesting?
Xiao-Li Huang, Xiao-Ying Jiang, Yu-Xuan Wang +3
We investigate the harvesting of quantum steering and its asymmetry between two static detectors locally interacting with a vacuum massless scalar field near an infinite, perfectly…
Harvesting asymmetric steering via non-identical detectors
Shu-Min Wu, Rui-Di Wang, Xiao-Li Huang +1
We investigate asymmetric steering harvesting phenomenon involving two non-identical inertial detectors with different energy gaps, which interact locally with vacuum massless scal…
Genuine N-partite entanglement in Schwarzschild-de Sitter black hole spacetime
Shu-Min Wu, Xiao-Wei Teng, Xiao-Li Huang +1
Complex quantum information tasks in a gravitational background require multipartite entanglement for effective processing. Therefore, it is necessary to investigate the properties…
