Entanglement and the geometry of spacetime

WebWe study the relationship between the geometry of spacetime and quantum informa-tion. This is motivated by recent insights which suggest that geometry is an emergent phenomenon in quantum gravity, and in particular that geometry is built from quantum entanglement. Part I of this thesis is focused on the relationship between area and entropy. WebMay 6, 2024 · Entanglement creates spacetime. At least that’s the proposal that current research in toy universes has inspired. “The emergence of spacetime and gravity is a mysterious phenomenon of quantum many-body physics that we would like to understand,” Swingle suggests in his Annual Review paper.
