[2301.09575] Black holes as tools for quantum computing by advanced extraterrestrial civilizations
Abstract:We explain that black holes are the most efficient capacitors of quantum information. It is thereby expected that all sufficiently advanced civilizations ultimately employ black holes in their quantum computers. The accompanying Hawking radiation is democratic in particle species. Due to this, the alien quantum computers will radiate in ordinary particles such as neutrinos and photons within the range of potential sensitivity of our detectors. This offers a new avenue for SETI, including the civilizations entirely composed of hidden particles species interacting with our world exclusively through gravity.
