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 the laws of physics.

We have opened [a Youtube channel] dedicated to our collaboration activities. The videos we have now include the videos of the colloquia. We expect that more videos will come up in the near future.
WHAT’S NEW
We will have the 11th public ExU Online Colloquium “Public ExU Colloquium” on May 11 (Mon.) 10:00 (JST). The speaker is Dr. Miles Stoudenmire (Center for Compuhtational Quantum Physics, Flatiron Institute). For details, please refer to the poster. If you have not registered yet, please register at our online event website at least three days prior to the colloquium. (It is not necessary to register again if you have done it already.)
The Principal Investigator of Publicly Offered Research ProjectE01, Takashi Takagi (University of Tokyo) has received the FY2026 MEXT Young Scientists Award. Congratulations. For details, please see [Link].
The Grant-in-Aid for Transformative Research Areas (A) “Extreme Universe” officially concludes today. We sincerely thank you for your tremendous support over the years. Thanks to your contributions, our members have produced numerous research achievements and successfully opened up new scientific frontiers. We will continue to share related updates through this account for approximately the next six months.
