In recent years, interest in quantum fundamentals has been on the rise, partly because of developments in quantum information science. Fundamental problems such as the violation of Bell inequalities, which had previously remained in the realm of philosophy of science, are essential for quantum teleportation, the security of quantum cryptography, and the basis for improving the speed of quantum computation. Quantum foundations are now given renewed consideration worldwide. It is of great benefit to the scientific community and to society in general that it has become much easier to participate in research into quantum foundations, giving more and more young students and researchers a chance to discuss quantum foundations and to contribute confidently to the frontiers of research. However, there is still a lack of events focusing on quantum foundations in Japan, and there are few opportunities for young people to present their research in a motivating and constructive atmosphere. This workshop was established to meet such needs.

The first edition of QF24, held on March 11-12, 2024, featured 18 oral presentations and 12 poster presentations. It attracted over 80 in-person participants and more than 100 online attendees, reaffirming the high level of interest in quantum foundations. Building on this success, we are pleased to announce that the second edition, QF25, will take place in March 10-11, 2025.

Keywords: interpretation of quantum mechanics, measurement problem, uncertainty, Bell's theorem, quantum nonlocality, entanglement, quantum measurement, quantum open system, irreversibility, general probability theory, fundamental of probability concept, formalization of quantum mechanics (quantum field theory), weak value, information and measurements, (quantum) contextuality, random number, information thermodynamics, quantum cryptography, quantum communication, quantum computation, quantum gravity, quantum cosmology, causality, time, etc.

1. Quantum Foundations invites a wide range of presenters.
2. We would like to provide an opportunity for young people, including students, to feel free to present their research.
3. Online presentations are acceptable, but face-to-face presentations will be given priority. Depending on the number of participants, poster presentations may also be held.
4. The presentation time will be 20-40 minutes plus 5-10 minutes for Q&A, depending on the workshop program.
5. Venue: IIS, The University of Tokyo (Kashiwa Campus, Large conference room "DAIKAIGISHITSU"), Hybrid event with Zoom online
6. Participation fee: face-to-face: 1000 JPY, online: free
7. Banquet: A banquet (reception) will be held on 3/10. The price is tentatively 2,500 JPY.
8. The workshops will be recorded for archival purposes. Photography (including screen shots) and video recording of lectures and posters by individuals are prohibited.
