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 will have the long-term workshop "Quantum Information, Quantum Matter and Quantum Gravity" from Sep. 4th to Oct. 6th at YITP, Kyoto. Application for travel support, VISA support, and giving presentations is closed. Registration for on-site participation is still open, but we may close the registration earlier than planned (July 31st) due to the venue's limited capacity. For details, please refer to [the webpage of the workshop].
The online registration is now open. Please see the details and register from [here].
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.
We will have the 17th online colloquium “Extreme Universe Colloquium” on June 6th (Tue) 19:00 (JST). The speaker is Prof. Harvey Reall (University of Cambridge). 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.)
We will have the 16th online colloquium “Extreme Universe Colloquium” on May 24th (Wed) 16:00 (JST). The speaker is Prof. Yasunobu Nakamura (University of Tokyo/RIKEN). 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.)

We will be holding the long-term workshop "Quantum Information, Quantum Matter, and Quantum Gravity" at Yukawa Institute for Theoretical Physics, Kyoto University from September 4th to October 6th this year. The registration for the on-site participants has begun. The deadline for applying for travel expenses and/or giving a presentation is May 31st. We look forward to your participation.

A dilution refrigerator with a superconducting magnet has been delivered to the laboratory led by Prof. Go Yusa, Tohoku University in our C01 group. The refrigerator enables us to make electric measurements in the GHz band while cooling the measured sample to at least 5mK (about minus 273.145℃). This equipment will be used to realize physical systems equivalent to expanding universes or black holes in semiconductors and explore the quantum universe from laboratory-level experiments.
