Question

I'm interested in characterizing the behaviour of measures of quantum information in strongly correlated quantum field theories which admit a gravity dual description, e.g through AdS/CFT duality. In a more broad sense, my question points towards the following: in my limited experience, I use to accept that a duality means that we don't have any right to give a physical meaning to one part of the duality and use the other part as a mere computational tool. I would like to be illuminated by some experts.

Explanation / Answer

This is an interesting question, which quite a few people (myself included) find fascinating, and by and large still remains to be explored. To my knowledge, the farthest this idea has gotten so far is in the work of my colleague, Mark van Raamsdonk: Comments on quantum gravity and entanglement and the essay Building up spacetime with quantum entanglement which won the GRF essay competition last year. If you have background in many body systems and their description in terms of quantum information, your input on this set of issues could be valuable.
