We aim to elucidate the "extreme universe" from the new perspective that all things are composed of "quantum information", going beyond the conventional understanding of "time, space, and matter" in physics. This "extreme universe" refers to the extreme conditions of the natural world, and includes the following three targets:

(i) quantum theory of Black holes (i.e. the limit of space),
(ii) quantum theory of Cosmology (i.e. the limit of time),
(iii) Dynamics of quantum matter (i.e. the limit of matter).

To solve these problems, we need the ultimate understanding of laws of physics.
