KDDI Group established KDDI VISION 2030, of which message is " The creation of a society in which anyone can make their dreams a reality, by enhancing the power to connect." Under KDDI VISION 2030, KDDI has been at the forefront in expanding the coverage area and increasing the speed of 5G, utilization of NTN, and so forth. In addition, we have been conducting research and development not only in technologies related to telecommunication fields but also in various technologies such as AI, security, and XR in order to provide new value-added services and support the DX for various industries and the sustainable growth of society.
This talk will introduce activities for creating new value-added use cases with partner companies using 5G, as well as our latest technologies aimed at addressing anticipated challenges and use cases in the Beyond 5G/6G era.

The realization of a sustainable society has become a global challenge. This is no exception for those who are engineers or researchers in microwave engineering and those who aim to implement microwave technology-based products in industry.
This special session aims to show the audience how and what kind of sustainable society can be achieved by using microwave technologies. First, a researcher who is working to solve social issues toward the realization of a sustainable society will present the social issues that need to be solved and how to solve them.
Next, we will discuss on the keynote theme of this MWE, "Challenges of Microwave Technology," that is, what microwave technology can do to realize a sustainable society and where microwave technology should go in the future, based on the themes of "Circular Economy," "Carbon Neutral," "Safety and Security," "Inclusive," and "Sustainable Society. Inclusive" and 'Diversity'.
This special session includes an introduction to the relationship between the workshop structure of MWE 2024 and the realization of a sustainable society, as well as its relationship to the exhibition at the Microwave Expo (exhibition hall).

The seminar, titled "Quantum Computers and Microwaves: Precision Technologies Shaping the Future Society," will explore the crucial role of microwave technology in the development and control of quantum computers. As quantum computing advances, the need for precise control over quantum bits (qubits) becomes paramount. This requires specialized microwave components that operate in extreme environments, such as cryogenic temperatures and ultra-high vacuum conditions, ensuring the stable operation of qubits.
The seminar will cover the latest developments in generating synchronized, multi-channel microwave pulses, which are essential for executing complex quantum gate operations. These advancements in microwave control systems are key to scaling quantum computers and enhancing their computational capabilities. Additionally, the seminar will highlight how quantum computers, with their unparalleled processing power, can be applied to solve optimization problems in microwave circuit design and other related fields. This interplay between quantum computing and microwave technology opens up new avenues for innovation, offering potential solutions to challenges that were previously insurmountable. Participants will gain insights into the current technical challenges, cutting-edge research, and future prospects of this interdisciplinary field.

The millimeter wave band, with its attributes of easy access to broad bandwidth, short wavelength, and strong straightness, is becoming increasingly significant in the field of communications. Post its application in 5G (5th Generation Mobile Communication System) for mobile communications, there has been a surge in discussions encompassing Non-Terrestrial Networks (NTN), including space-based systems, for future communication technologies. In sensing applications, due to its material penetrability and high resolution, it is expected to be applied to non-contact, non-destructive high-precision tomographic imaging.
In this session, we will introduce the latest trends in research and development of semiconductor devices, which are essential for the social implementation of various scenes of next-generation communication and sensing using the millimeter wave band.
