BLHW03 - Bridges between holographic quantum information and quantum gravity

A careful analysis of the gravitational constraints reveals that quantum gravity localizes information differently from ordinary quantum field theories—- an effect called the holography of information. We review the results obtained so far for asymptotically flat spacetimes, asymptotically anti-de Sitter spacetimes, and asymptotically de Sitter spacetimes. About some simple states, it is surprising that these effects are visible in perturbation theory. In a different regime, we explain the significance of the holography of information for understanding black-hole evaporation and the information paradox. We discuss several interesting open questions.
