A Postquantum Theory of Classical Gravity - Theoretical Background

Explore a comprehensive lecture on the theoretical background of a postquantum theory of classical gravity presented by Jonathan Oppenheim at the International Centre for Theoretical Sciences. Delve into cutting-edge concepts at the intersection of quantum information, quantum field theory, and gravity as part of a broader program on these topics. Gain insights into the AdS/CFT correspondence, the emergence of spacetime and gravity from quantum information dynamics, and the application of quantum information theory to long-standing problems in quantum gravity. Examine the connections between general relativity and quantum information theory, including their impact on black hole physics and information scrambling in chaotic quantum systems. Investigate how quantum information theory has provided new perspectives on quantum field theories and many-body dynamics, leading to novel proofs and constraints. Engage with topics such as quantum error correction, complexity growth, multiparty entanglement in holography, gravitational constraints on quantum information localization, and tensor network models in condensed matter and quantum gravity.
