Abstract
Abstract The first investigation of tripartite entanglement harvesting in the vicinity of a black hole is carried out. Working in the context of a static Bañados–Teitelboim–Zanelli (BTZ) black hole spacetime the authors find that it is possible to harvest tripartite entanglement in regions where harvesting of bipartite entanglement is known to be impossible due to intense Hawking radiation. In these situations, it implies that the harvested entanglement is of the Greenberger–Horne–Zeilinger (GHZ) type.
