Information Vol. 18, No. 2, pp. 49–56, Feb. 2020. https://doi.org/10.53829/ntr202002in1 Report on NTT R&D Forum 2019AbstractNTT R&D Forum 2019 was held at the NTT Musashino Research and Development Center on November 11–15, 2019 (November 11 and 12 were set aside solely for the press and NTT Group employees). This article provides an overall of the forum. Keywords: R&D forum, IOWN, smart world
1. Forum overviewThe NTT Group is seeking to resolve social issues as Your Value Partner. In May 2019, it announced the Innovative Optical and Wireless Network (IOWN), a photonics-based concept aimed at providing a high-capacity, low-latency, and energy-efficient information communication infrastructure capable of supporting sustainable growth. NTT R&D Forum 2019 introduced the latest results of research activities carried out based on this concept through lectures and exhibits presented under the theme of “What’s IOWN? - Change the World.” 2. Lectures and workshopsOn November 13, NTT president and CEO Jun Sawada gave a keynote lecture entitled “Towards the Era of IOWN” (Photo 1). By comparing and contrasting a recycling society developed during the Edo Period in Japan with European societies during the Industrial Revolution, which was designed to encourage economic growth, he stated that NTT is seeking a society in which innovations bridge today’s social divisions arising from differences in civilization or thinking. Increasing consumption of electrical energy represents a technical constraint on sustainable development. The technical foundation of IOWN is the extremely energy-efficient photonics-electronics convergence technology that NTT is developing. Based on this technology, NTT is developing the All-Photonics Network, which will also pave the way for an ultimate future network that incorporates quantum communication and quantum encryption. As Digital Twin Computing advances, interactions within the cyberworld will become possible. When the real space works in concert with the new cyberspace, how will social institutions, the purpose of and joy in life, ethics, and responsibility manifest themselves? NTT will collaborate with Kyoto University in studying these questions, which represent a new way of looking at the world. Mr. Sawada also described Cognitive Foundation®, which automatically links various information and communication technology (ICT) resources to enable a network to evolve autonomously, and introduced NTT’s involvement in the Smart City project in Las Vegas as an example.
Looking towards the future of communication, NTT, Intel, and Sony announced the establishment of the IOWN Global Forum, an international forum that promotes photonics-related research and development (R&D) based on photonics-electronics convergence. Sixty-five companies, the majority of which are from outside Japan, are currently considering to participate in it. Mr. Sawada ended his address by inviting partners to participate in NTT projects aimed at creating a smart world. The president’s keynote lecture was followed by a presentation by Katsuhiko Kawazoe, NTT senior vice president and head of the Research and Development Planning Department, entitled “What’s IOWN? - Change the World.” The vision of IOWN is to create an innovative information processing base that will carry out vastly expanded information processing and make it possible to break through conventional technical constraints such as power consumption. IOWN consists of three elements: All-Photonics Network, which dramatically enhances the potential of the information processing base; Digital Twin Computing, which opens a new horizon for services and applications.; and Cognitive Foundation, which optimally harmonizes all ICT resources. Wireless access technology in IOWN will also penetrate everywhere, e.g., under the sea, in the air, or in outer space, resulting in a world of connected everywhere. NTT’s activities towards this goal include world-leading high-capacity wireless transmission, undersea wireless communication, and wireless transmission in outer space, with the latter being undertaken as a joint research project with Japan Aerospace Exploration Agency (JAXA). To illustrate a world made possible by IOWN, Mr. Kawazoe introduced a project involving a company, academic institution, and local government, i.e., NTT, Hokkaido University, and Iwamizawa City in Hokkaido. The aim of this project is to promote world-leading smart agriculture using cutting-edge agricultural robot technology and ICT. He concluded his presentation with a declaration that those involved in NTT R&D are committed to thinking outside the box and pursuing the welfare and prosperity of humankind propelled by a tremendous zeal for technical innovation given the urgent need to protect the global environment and ensure sustainable development. Two special sessions were held on November 14, and four on November 15. In the first session on November 14, Kazuhiro Gomi, president and CEO of NTT Research, Inc., introduced the innovation strategy of NTT Research, which is responsible for the globalization of NTT R&D, and its positioning in the IOWN initiative under the title of “Upgrade Reality - Reality in IOWN Concept.” In the second session, the directors of the three laboratories that make up NTT Research gave an overview of their respective activities. Tatsuaki Okamoto, director of Cryptography & Information Security Laboratories (CIS Labs), reported that their aim is to create a world-leading encryption laboratory and that they already have a pool of top researchers, who they hope will form a dream team in the areas of cryptography theory and blockchain. For this purpose, they will collaborate with NTT Security Platform Laboratories. Hitonobu Tomoike, director of Medical & Health Informatics Laboratories (MEI Labs), said that they are focusing on precision medicine as it enables diagnosis and healthcare to be tuned to the characteristics of each individual. For this purpose, they will apply artificial intelligence (AI), the Internet of Things (IoT), and data science in their research on health and diseases while placing the highest priority on patients. Next, Yoshihisa Yamamoto, director of Physics & Informatics Laboratories (PHI Labs), presented the challenge of fusing the principles of quantum mechanics and brain-based information processing with light. Their long-term research target is to understand how humans carry out advanced information processing, such as recognition and decision-making, as well as the nature of consciousness, by analyzing the relationships between these two principles. Lastly, a panel discussion was held with Director Okamoto of CIS Labs, Director Tomoike of MEI Labs, and Deputy Director Satoshi Kako of PHI Labs as panelists and with President Gomi acting as the moderator (Photo 2). They discussed the advantages that Silicon Valley, where NTT Research is located, offers, such as the availability of top-notch and highly motivated experts and interdisciplinary environments, and their determination to advance their research capabilities on the basis of NTT’s traditions.
On November 15, Professor Noboru Noguchi, program director of Fundamental Agriscience Research, Research Faculty of Agriculture, Hokkaido University, gave a presentation entitled “Smart Agriculture toward Society 5.0.” He spoke of a smart agriculture project that uses cutting-edge agricultural robot technology and ICT. This project is being undertaken based on an agreement involving NTT, Hokkaido University, and Iwamizawa City (Photo 3). Then, Ryutaro Kawamura, director of NTT Service Innovation Laboratory Group, gave a talk entitled “The Digital World of Humans and Society – Digital Twin Computing.” He envisioned how the acceleration of digitalization will change the world and identified key technologies that will make this change possible. This was followed by a presentation, entitled “Innovative Network Focused on 2030 (Beyond 2020),” by Arata Itoh, director of NTT Information Network Laboratory Group. He introduced the Group’s research initiatives undertaken within the context of the IOWN concept and the latest research cases. Lastly, Tetsuomi Sogawa, director of NTT Science and Core Technology Laboratory Group, presented a lecture entitled “Basic Research Supporting All-Photonics Network.” He elaborated on photonics-electronics convergence devices that make high-speed and ultra-power-efficient operation possible; innovative photonics devices that support high-capacity optical transmission; LASOLVTM, a new physical computer based on optical communication technologies; and an optical lattice clock network that serves as a next-generation frequency/time reference infrastructure.
