### Description

The $AdS_4$ spacetime is of much interest to physicists, because of its relevance to the AdS/CFT duality. Very little is known
about how to extract quantum correlations from the AdS vacuum, a procedure called entanglement harvesting.
Using a new and general theorem, we calculate the entanglement harvested by a pair of Unruh-DeWitt detectors coupled to a conformal scalar vacuum of $AdS_4$, in two physical scenarios: one where both detectors are in geodesic motion, and one where both detectors are static. As in flat space, we find that for any separation, there exists an energy for which entanglement harvesting is possible. We also characterize the dependence of the entanglement harvested on separation in time and space, for different values of curvature. Our calculations demonstrate that the theorem may be used effectively to simplify calculations in much more general spacetimes.
