The deepening relationship between informatics, computer science, and physics is drawing attention. The relationship between the energy efficiency of information processing and the laws of physics has been debated for a long time. Two-way exchanges in the direction of understanding the laws of physics from methods are becoming active in both theory and experiment.

In this proposal, we will promote interdisciplinary research that bridges informatics/computer science and physics, aiming for growth in this emerging field and breakthroughs in physics/ informatics. suggest.

• （1）Applying concepts and methods of physics to informatics and computer science
• （2）Apply concepts and methods of informatics and computer science to physics
• （3）Mathematics that connects physics and informatics/computer science

From the point of view of physics, a real computer is a non-equilibrium, open system, and it is necessary to go back to the theoretical framework to deal with the limits of energy efficiency. New concepts and discoveries in physics are highly likely to lead to breakthroughs in the form of new computational principles and new devices. Expanding the frontiers of informatics and computer science is essential for the long-term development of IT from the perspective of human resource development. Furthermore, the academic foundations and tools created by this research and development will spread to a wide range of fields, and are expected to contribute to the resolution of social issues through low power consumption calculations and secure information processing.

In addition to the research and development and maintenance of basic technologies, the government needs to work on developing human resources and organizations that will lead new fields and fostering communities. This proposal proposes a promotion method from the following three aspects.

• （1）Establishment of a leading research group
• （2）Building an international research center
• （3）Long-term project

This research and development area is in an embryonic state, and research communities are divided internationally. Therefore, first of all, we need a place where we can share awareness and discuss issues across fields and communities, such as between mathematics/information and physics, between quantum information and statistical mechanics. Also, in order to conduct such discussions effectively and efficiently, it is considered to be an important factor to physically gather in the same place. It is desirable not only to meet temporarily at workshops and research groups, but also to foster discussion within a shared sense of belonging to specific research institutes and organizations. In addition, fundamentally important research often does not produce results in a short period of one to three years. More time may be needed for interdisciplinary research. It is desirable to have a position that allows research to proceed for a five-year term and can be renewed unconditionally for up to ten years if there are no particular problems.
