Black holes, information and decoherence
arXiv:0903.2258 · doi:10.1103/PhysRevD.79.124037
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.
