Abstract: (Springer)
The projective measurements on a vacuum performed by Rob, who hovers near the event horizon of the Einstein–Gauss–Bonnet black hole, will result in an entangled state for Alice moving along a geodesic. We show that the entanglement of the produced state is greatly dependent on Rob’s projective measurements and the parameters of the black hole, such as the horizon radius rHr_H, Gauss–Bonnet coefficient α\alpha and dimension d of the spacetime. We also present the conditions for Alice to get the maximal entangled state in this process.
