Mikio Kozuma
Professor, Quantum Navigation Unit, Institute of Innovative Research, Tokyo Institute of Technology

Toward the implementation of an ultra-precise inertial navigation system
-Latest research results to improve the precision of non-GPS navigation-

Professor Mikio Kozuma introduced a method of improving the performance of inertial navigation, which is the ability to determine one's own position and posture by using a gyroscope that utilizes the quantum effect, and its application to autonomous underwater vehicles (AUVs).

Mamiko Kujiraoka
Research Scientist, Computer and Network Systems Laboratory, Corporate Research & Development Center, Toshiba Corporation

Research and development of Toshiba quantum cryptography
-Toshiba QKD systems and field trials-

Mamiko Kujiraoka spoke about quantum cryptography, and more specifically quantum key delivery (QKD), in which information security is guaranteed based on the principles of quantum mechanics. She explained that Toshiba has successfully developed a quantum cryptosystem that enables high-speed key delivery and long-distance transmission, and that the company aims to realize a quantum cryptosystem network for a wider area and on a larger scale.

Mutsuko Hatano
Professor, School of Engineering, Tokyo Institute of Technology

Pink diamond: Potential of diamond quantum sensors for super smart society
-Introduction to possibilities of diamond quantum sensors from healthcare to industrial applications-

Professor Mutsuko Hatano introduced the process of promoting the development of quantum sensors using the properties of pink diamonds in practical devices. She highlighted their potential application not only in electronic devices, but also in fields such as medicine, and provided examples of practical experiments. In terms of research and development, all of these technologies are aiming to achieve Society 5.0, and human resource development will be very important in terms of long-term progress, Hatano mentioned.

Panel discussion

Following the lectures, a panel discussion moderated by Associate Professor Jun Yoneda from Tokyo Tech Academy for Super Smart Society focused on the future of quantum science. Joining the four speakers as panelists were Associate Professor Tetsuo Kodera from the School of Engineering and Associate Professor Toru Hirahara from the School of Science. The panelists discussed a wide range of topics, including the status and challenges regarding the practical application of quantum science, and related human resource development. The participants reaffirmed the important role of the SSS Promotion Consortium to bring academia together with the private sector to address these issues, and to bring students at various levels of study closer to quantum science.

After the panel discussion, Professor Nobuyuki Iwatsuki, who chairs the Consortium Steering Committee, gave a briefing on the consortium's progress. His message was followed by some closing words from Tokyo Tech's Executive Vice President for Education Tetsuya Mizumoto.

Feedback regarding the event from participants was positive. Some said that they greatly appreciated the detailed yet easy-to-understand explanations on quantum science from their colleagues. Others stated that the content of the forum would be very useful for the progress of their own R&D work, and look forward to future developments.

Super Smart Society Promotion Consortium

Tokyo Tech founded the Super Smart Society Promotion Consortium in October 2018 to advance the realization of Society 5.0 through a next-generation education and research platform that integrates the development of human resources with joint research and development involving participating institutions. Currently, the consortium consists of 38 members including corporations, research institutions, local government bodies, and individuals.

Tokyo Tech Academy for Super Smart Society

Through a seamless, interdisciplinary academic program that spans the master's and doctoral levels, the Tokyo Tech Academy for Super Smart Society develops professionals who can integrate physical space and cyber space while combining cutting-edge technologies in fields such as quantum science and artificial intelligence.
