- Abstract summary: Hawking radiation, whose spectrum was calculated considering particles scattering off black holes, is connected to the paradox of the loss of information falling into them.
We show that the scrambling power of the gravitational field of a black hole is negligible with respect to the scrambling power of flat space-time.

- Abstract: Black holes are a recently observed theoretical prediction of General
Relativity, characterized by event horizons, from which information cannot
escape. Examined through the lenses of quantum mechanics, they can radiate at a
definite temperature inverse to their mass and horizon radius. Hawking
radiation, whose spectrum was calculated considering particles scattering off
black holes, is connected to the paradox of the loss of information falling
into them. Information can become non-fungible, due to scrambling. We
demonstrate this feature not to be restricted to curved space-times: soft
radiation scattering in a flat space-time does scramble information as well. To
this end, we compute the scrambling of information through the tripartite
mutual information in a scattering process off a black hole and compare it with
the flat space-time analog. We show that the scrambling power of the
gravitational field of a black hole is negligible with respect to the
scrambling power of flat space-time.

Black holes not only emit radiation spontaneously, but also respond to infalling matter and radiation by emitting approximate clones of those fields in a stimulated manner.
I show how stimulated emission turns the black hole into an almost optimal quantum cloning machine.
I speculate about possible observable consequences of stimulated emission of radiation in black holes.
