QUPosium2023 was held on December 11th-13th, 2023 at the Epochal Tsukuba International Congress Center in Tsukuba, Japan. This was QUP’s 2nd International Symposium on Quantum-field Measurement Systems for Studies of the Universe, Particles, and Other Applications (QUPosium2023). The huge success of the conference was due to the attendance of prominent scientists from all over the world in particle physics, astrophysics, condensed matter physics and measurement science. This open forum discussed the most exciting developments and ideas towards addressing five major mysteries of the Universe:

1. What drives inflation and causes accelerated expansion of early Universe?
2. Why is there more matter than antimatter in the Universe?
3. What are the fundamental properties of neutrinos?
4. What is the nature of dark matter?
5. What is dark energy that causes accelerated expansion in late Universe?

The free open discussion discovered overlaps in methodologies across various expertise and exchanged points of views on how to integrate efforts to produce new academic and social values.

Poster presentations and presentations are available to review.
