Abstract We propose the information-theoretic quantity of geometric quantum discord (GQD) as an indicator of the factorization properties of a given quantum system.In hot ole miss girls particular, we show how non-vanishing discord implies that the corresponding partition function does not factorize, both for generic pure states and the thermofield double state as a state with a known geometric dual in light of the AdS/CFT correspondence.Via this analysis, we give a novel interpretation to the thermomixed double state as waist deep dvd the best purely classical approximation of the Einstein-Rosen bridge.

We connect the non-vanishing of GQD with the existence of wormhole microstates.
