Abstract
We study the properties of quantum entanglement and teleportation in the background of stationary and rotating curved spacetimes with extra dimensions. We show that a maximally entangled Bell state in an inertial frame becomes less entangled in curved space due to the well-known Hawking–Unruh effect. The degree of entanglement is found to be degraded with the increase in the extra dimensions. For a finite black hole surface gravity, the observer may choose a higher frequency mode to keep high level entanglement. The fidelity of quantum teleportation is also reduced because of the Hawking–Unruh effect. We discuss the fidelity as a function of extra dimensions, mode frequency, black hole mass and black hole angular momentum parameter for both bosonic and fermionic resources.
