Grab it Explore the intricate relationship between entanglement and the emergence of semiclassical spacetime in string theory through this 55-minute conference talk delivered at the Workshop on "Large-N Matrix Models and Emergent Geometry" at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the significance of Matrix Quantum Mechanics (MQM) as a crucial toy model for understanding how locality emerges on sub-AdS lengthscales and in compact dimensions within AdS/CFT. Examine recent developments in entanglement studies within matrix quantum mechanics and discover how geometric subregions in the stringy bulk can arise from non-geometric color partitions of the quantum mechanical boundary. Gain insights into large-N D-brane holography as a promising candidate for non-perturbative string theory definition, and explore concepts such as Susskind-Uglum open string edge modes, holographic subregion duality, entanglement wedge reconstruction, and entanglement islands.
