    "abstract": "We investigate the Hawking effect on entangled fields. By considering a\nscalar field which is in a two-mode squeezed state from the point of view of\nfreely falling (Kruskal) observers crossing the horizon of a Schwarzschild\nblack hole, we study the degradation of quantum and classical correlations in\nthe state from the perspective of Schwarzschild observers confined outside the\nhorizon. Due to monogamy constraints on the entanglement distribution, we show\nthat the lost bipartite entanglement is recovered as multipartite entanglement\namong modes inside and outside the horizon. In the limit of a small-mass black\nhole, no bipartite entanglement is detected outside the horizon, while the\ngenuine multipartite entanglement interlinking the inner and outer regions\ngrows infinitely.",
