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…
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…
Advantages and disadvantages of maximally entangled states in dilaton black hole background
Zhen Yang, He Cheng, Si-Han Li
We investigate quantum entanglement and coherence for four classes of Bell-like fermionic states in the vicinity of the event horizon of a Garfinkle-Horowitz-Strominger (GHS) dilat…
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…
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…
Genuinely accessible and inaccessible entanglement in Schwarzschild black hole
Shu-Min Wu, Xiao-Wei Teng, Jin-Xuan Li +3
The genuine entanglement of Dirac fields for an N-partite system is investigated in Schwarzschild spacetime and the analysis is carried out using the single-mode approximation. Due…
