Black Holes as Ultra-Efficient Quantum Computers: Hawking Radiation as a New Technosignature for SETI

To the point

Gia Dvali and Zaza N. Osmanov propose that ultra‑advanced civilizations could use black holes as highly efficient quantum computers, with Hawking radiation acting as a detectable sign of their activity and IceCube‑like detectors catching the byproducts of computation, thereby expanding SETI to search for the footprints of advanced information processing rather than only intentional signals.
