The black hole information paradox — whether information escapes an evaporating black hole or not — remains one of the greatest unsolved mysteries of theoretical physics. The apparent conflict between the predictions of classical General Relativity and unitarity of quantum mechanics has long been expected to find its resolution in the deep quantum gravity regime. Recent developments in holographic entanglement entropy, however, have shown that a uniquely semiclassical analysis of gravitational physics has signatures of unitary evolution. I will describe this recent progress and discuss some potential new avenues for understanding the mechanism via which information can escape.
