Front-line Researchers

Seiichiro Tani, Senior Distinguished Researcher, NTT
Communication Science Laboratories▼OverviewResearch toward the development of a practical quantum computer began morethan 30 years ago in the 1980s, and it is now entering a new phase. The Ministry ofEducation, Culture, Sports, Science and Technology in Japan recognizes thesignificance of this development and has included 3.2 billion yen in its budget
request as a development fund for photonics-quantum technology. SeniorDistinguished Researcher Seiichiro Tani of NTT Communication Science
Laboratories has had many world-first achievements in this field. The quantum
computer is attracting attention as a driver of future trends, so we asked him to tell
us about the current state of quantum computer research and some researchachievements. We also asked him his views on how a researcher should approach
the work of research.

NTT’s Increased Focus on Open Source Software▼AbstractElectrical Current Generation by Sorting Thermal NoiseThe emergence of new information technology (IT)applications such as artificial intelligence, the Internet ofThings, and software-defined infrastructures is stimulating
more use of open source software (OSS), and consequently,
the skills needed for using OSS are broadening. While legacy
IT applications would require skills in using only a few standard
OSS packages, these new application areas require the ability to select software modules from many
choices and integrate them into a system tailored to a company’s or customer’s requirements. Suchintegration activities often require collaboration with OSS communities. Additionally, because these
activities incur costs, it is also important to develop business strategies to leverage OSS and gain arewarding return.

Electrical Current Generation by Sorting Thermal Noise▼Abstract

We have achieved the operation of Maxwell’s demon with an electricaldevice, which is a feedback operation based on single-electron motion.
Maxwell’s demon is related to the lower bound of energy consumption
in electrical devices and power generation efficiency in small systems.
We therefore anticipate that this achievement will contribute to creating
nanoscale energy-efficient electrical devices.
