In recent years, the AdS/CFT correspondence has led to a paradigm shift in the quest for a theory of quantum gravity. In this new approach, spacetime and gravity are viewed not as fundamental, but as emergent descriptions of the dynamics of quantum information in an underlying, microscopic quantum system. The resulting theory has led to a novel confluence between two different subjects, namely general relativity and quantum information theory. This confluence has enriched both the subjects. On the one hand, tools from quantum information theory such as quantum error correction have led to ground-breaking progress on long-standing problems in quantum gravity such as the black hole information paradox. On the other hand, black hole physics has led to fundamental insights on information scrambling in chaotic quantum systems.

Quantum information theory has also provided a new window into the rich world of quantum field theories and many-body dynamics. Fundamental inequalities governing the structure of quantum information have led to novel proofs of known constraints on QFTs such as the c-theorem and the averaged null energy condition, as well as to previously unknown constraints such as the quantum null energy condition. In the world of many-body quantum systems, entanglement structure has provided a robust characterization of phases of quantum matter.

This program seeks to bring together leading experts working at the intersection of quantum gravity, quantum information theory and many-body physics in the hope of ushering in a new wave of progress in this multidisciplinary field. The program will focus on the following broad themes:

Quantum error correction, the emergence of spacetime, and the black hole interior
Complexity growth and saturation and its manifestation in gravity
Multiparty entanglement and its role in holography
The importance of gravitational constraints in the localization of quantum information.
Tensor network models in condensed matter and quantum gravity

Prof. Tadashi Takayanagi will be delivering three Infosys-ICTS Chandrasekhar lectures as part of this meeting.

Eligibility Criteria: For PhD students, postdoctoral fellows, and faculty working in related areas.

Accommodation will be provided for outstation participants at our on campus guest house.

ICTS is committed to building an environment that is inclusive, non discriminatory and welcoming of diverse individuals. We especially encourage the participation of women and other under-represented groups.
