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 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…
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…
