Latest Trends in 400- and Beyond 400-Gbit/s Ethernet Standardization in IEEE 802.3▼Overview
The NTT Service Innovation Laboratory Group aims to create a world in which all
people are happy and can live their lives safely, securely, and healthy. Its threelaboratories (i.e., NTT Human Informatics Laboratories, NTT Social Informatics
Laboratories, and NTT Computer and Data Science Laboratories) research anddevelop technologies for integrating cyber and physical spaces to create a world inwhich a harmonious relationship between the Earth, society, and individuals isbuilt. We interviewed Tomoyoshi Oono, senior vice president, head of the NTT
Service Innovation Laboratory Group, who is orchestrating the laboratory group’s
efforts to solve social issues and create new value by thinking outside the box,
about his new mission and the qualities required of top management.

Front-line Researchers

William John Munro, Senior Distinguished Researcher, NTT
Basic Research Laboratories▼OverviewResearchers at NTT Basic Research Laboratories are aiming to create newtechnologies harnessing the power of quantum mechanics. In November 2020, they
proposed a method for compressing quantum circuits to enable high-speed quantum
computation and the miniaturization of quantum computers in the US scientificjournal Physical Review X. In February 2021, the British scientific journal Nature
Communications published a paper on the demonstration of a high-speed quantum
random-number generator that achieves the highest levels of security by using theworld’s first practical optical device. We interviewed William John Munro, a seniordistinguished researcher at the laboratories and leading figure in the broad field ofquantum technology, about his research activities and his attitude as a researcher.

Network-service Technologies Enabled by the All-Photonics Network for IOWN

Network-service Technology Enabled by the All-Photonics
Network▼Abstract
To implement the Innovative Optical andWireless Network (IOWN), an advanced
network that can efficiently process a large
amount of data incomparable with theconventional Internet is required. To satisfy
this requirement, NTT is researching anddeveloping the epoch-making All-Photonics
Network (APN), which will make maximum
use of photonics-electronics convergence
technology. This article describes activities
related to function-dedicated network(FDN) architecture and the network-service
technology that can be implemented on an
FDN to provide various services via theAPN.
