NTT R&D FORUM 2025 Photo Report---Technologies that will revolutionize everything from telecommunications to the real world

NTT held the NTT R&D FORUM 2025 "IOWN∴Quantum Leap" for five days from November 19 to 21 and November 25 and 26, 2025. The key message of the event was "Quantum Leap," meaning a quantum leap forward in 2025, the 100th anniversary of the birth of quantum science. The lectures and exhibits showed what kind of technologies and future awaits us when AI and quantum computers are fused with IOWN (Innovative Optical and Wireless Network), an optical network, as one axis. The Musashino Research and Development Center, which served as the venue for the event, attracted many visitors, including prominent figures from various fields, and provided an opportunity to experience the current state of research and technology that will be indispensable to society in the future. In this article, we report in the form of a photo report on the technical exhibits, which included IOWN, optical quantum computers, digital twins, mobility, energy watt-bit linkage, and much more.
