[Report] QI2025 / 8th IFQMS
In 2025, marking the 100th anniversary of quantum mechanics and designated as the “International Year of Quantum Science and Technology (IYQ)” by the UN and UNESCO, Quantum Innovation 2025 was held from Tuesday, July 29 to Friday, August 1, 2025, at Congres Square Grand Green Osaka in conjunction with Expo 2025 Osaka, Kansai. As a joint program, the 8th International Forum on Quantum Metrology and Sensing (8th IFQMS) was held at the same venue from July 29 to 31.
Additionally, on July 28, the QI2025 Satellite Workshop on Solid-state/Nano Quantum Sensing was held at the Suita Campus of The University of Osaka.
The IFQMS was launched in 2019 as part of the international collaboration and young researcher development initiative under the MEXT Quantum Leap Flagship Program (Q-LEAP) for Quantum Metrology and Sensing. Celebrating its 8th edition, this event promoted interdisciplinary exchanges to foster innovation through quantum metrology and sensing sessions centered on solid-state quantum sensors, as well as a joint poster session.

QI2025 Satellite Workshop on Solid-state/Nano Quantum Sensing (July 28)
As a satellite workshop of QI2025 / 8th IFQMS, the QI2025 Satellite Workshop on Solid-state/Nano Quantum Sensing was held at the Suita Campus of The University of Osaka (Chair: Prof. Yoshie Harada, The University of Osaka).
This workshop featured presentations by four speakers, including invited speakers Dr. Huan-Cheng Chang and Dr. Ronald Ulbricht from QI2025 / 8th IFQMS. Participants brought posters related to Solid-state/Nano Quantum Sensing from the QI2025 Poster Session for technical discussions, aiming to nurture young researchers and promote research exchange. Additionally, a laboratory tour of Prof. Harada’s lab was conducted.
