Project Title

Measures of Holographic Information

Project Summary

Whilst information is a concept we have natural intuition for in everyday circumstances, it is less tangible when one asks questions in a microscopic quantum theory. In recent years the subject of quantum information has grown significantly and now one has the mathematical tools to quantify information in a quantum mechanical system. At the same time, inspired by developments in string theory and black holes, one has learnt that gravitational theories are holographic. This means that one can describe them by completely different quantum mechanical degrees of freedom. This is at the heart of the famous gauge/gravity correspondence which treats the gravitational universe as a hologram. While the correspondence has been immensely useful in characterizing many aspects of gravitational physics and also quantum dynamics, we are far from having a complete understanding of this holographic picture. The project aims to employ techniques from the realm of quantum information to address our ignorance about the holographic map. In an explicit sense we would like to crack this holographic code and by doing so unearth the fundamental aspects of how spacetime, geometry, and quantum dynamics are unified in a complete theory.
