Abstract: Formulating quantum gravity is one of the final goals of fundamental physics. Recent progress in string theory brought a concrete formulation called AdS/CFT correspondence, in which a gravitational spacetime emerges from lower-dimensional non gravitational-quantum systems, but we still lack understanding how the correspondence works. At this end, I discuss similarities between quantum gravity and deep learning architecture, by regarding the neural network as a discretized spacetime. The application of machine learning in physics has been successful in some subjects, which I will review, and I use it to implement the AdS/CFT framework into a deep learning architecture, and show the emergence of a curved spacetime as a neural network, from a given teacher data of quantum systems.

The Bethe Forum "Multihadron Dynamics in a Box - A.D. 2022", postponed from February 21-25, 2022, will take place in the bctp as a follow-up event of the conference "Lattice2022" in Bonn. The organizers are M. Mai (Bonn), U.-G. Meißner (Bonn / Jülich), A. Rusetsky and C. Urbach (both Bonn).
