Aiming to Become a Visible Researcher by Taking Up Challenges without Fear of Failure

Green innovation involves creating new solutions to environmental problems and sustainable development, and research and development of innovative technologies in the fields of the environment, resources, and energy is being conducted worldwide to create a low-carbon and circular society. We interviewed Yoshitaka Taniyasu, a senior distinguished researcher at NTT Basic Research Laboratories, who has produced world-class research results concerning functional materials for green innovation, about his achievements and attitude as a researcher.

Underwater Acoustic Communication Technology for Wireless Remotely Operated Vehicles

Toward the 6th-generation mobile communication system, extreme coverage extension is expected to provide wireless communication services in the sky, at sea, and in space, which are regions not serviced by mobile communication systems. To achieve extreme coverage extension to the sea, NTT Network Innovation Laboratories is investigating higher-speed, longer-distance, and more stable underwater acoustic communications. In this article, we introduce our underwater acoustic communication technology and the feasibility demonstration of the world's first fully wireless remotely operated vehicle applying this technology.

Applying Optical Oscillator Networks to Diverse Problems as the First Step to Information Processing Systems of the Future

In the field of computer science requiring advanced information processing, an algorithm called simulated annealing is widely used to derive optimal solutions from a combination of numerous options in a network. However, in an era in which increasingly complex networks are coming to be constructed, any approach based on conventional methods is reaching its limits. To break down this wall, information processing techniques that can be applied to a variety of physical systems are being proposed. In this interview, we talked with NTT Distinguished Researcher Takahiro Inagaki about his research on new computing systems using optical technologies.
