Black Holes as Quantum-Information Capacitors: Democratically Emitted Hawking Radiation and a New SETI Technosignature
To the point
Gia Dvali and Zaza N. Osmanov propose that black holes can act as extremely efficient quantum computers, with Hawking radiation coming out evenly across particle types, so advanced civilizations could use black holes for computation and emit detectable particles like neutrinos and photons, opening a new SETI possibility even for civilizations that interact with us only through gravity.
