Grant-in-Aid for Transformative Research Areas(A) 2021 (Extreme Universe, Head Investigator Tadashi Takayanagi) has been adopted.

The purpose of this collaboration project “Extreme Universe” is to develop interdisciplinary researches which bridge between quantum information theory and various topics of physics, such as quantum gravity, cosmology and condensed matter physics. The goal of this project is to understand three fundamental problems of Extreme Universe, namely, (1) Quantum aspects of black holes (B-group), (ii) Quantum cosmology (C-group) , and (iii) Quantum Many-body dynamics (D-group), in the light of quantum information theory (A-group) as alphabets which describe laws of physics.
