Degradation of entanglement between two accelerated parties: Bell states under the Unruh effect

B Richter, Y Omar - Physical Review A, 2015 - APS
We study the entanglement of families of Unruh modes in the Bell states| Φ±〉= 1/2 (| 00〉±|
11〉) and| Ψ±〉= 1/2 (| 01〉±| 10〉) shared by two accelerated observers and find …

Entanglement harvesting of inertially moving Unruh-DeWitt detectors in Minkowski spacetime

C Suryaatmadja, RB Mann, W Cong - Physical Review D, 2022 - APS
