The black hole information paradox and macroscopic superpositions

TL;DR

This paper explores the experimental requirements to test if black holes destroy information, revealing that such tests must involve detecting macroscopic superpositions, linking black hole information loss to fundamental quantum measurement issues.

Contribution

It demonstrates that testing black hole information loss necessitates capabilities to detect or manipulate macroscopic superpositions, connecting quantum foundations with black hole physics.

Findings

Testing black hole information loss requires macroscopic superposition detection.

Experimentally probing black hole information involves addressing decoherence and wavefunction collapse.

Links quantum measurement problems with black hole information paradox.

Abstract

We investigate the experimental capabilities required to test whether black holes destroy information. We show that an experiment capable of illuminating the information puzzle must necessarily be able to detect or manipulate macroscopic superpositions (i.e., Everett branches). Hence, it could also address the fundamental question of decoherence versus wavefunction collapse.
