Stanley Electric, a Japanese supplier of automotive headlights that often went unnoticed by investors before the novel coronavirus, possesses ultraviolet sterilizing technology considered crucial in preventing another outbreak.

Japanese developers unveiled Wednesday a prototype of the magnetic-levitation bullet train that is capable of deriving onboard power completely wirelessly.

Water is a familiar substance that is present virtually everywhere. The properties of the first few layers of water molecules in contact with the surface of materials (called ‘surface water’) are especially important in materials science. In a recent study led by Prof Takahiro Yamamoto of Tokyo University of Science, scientists employed statistical data analysis tools to reveal what happens to water molecules on top of graphene.

Toshiba is planning to launch quantum cryptography services in the U.S. by September, first targeting the financial and medical sectors as the company looks for a new way to drive growth.

It is one of the nightmares of the "drone age": waves of unmanned aircraft overwhelming defenses to unleash death and destruction. An agency under Japan's Defense Ministry is making progress toward countering the threat.

Japan and the United States, aiming to beat China in the race to develop quantum computers, signed an agreement on Dec. 19 to partner on next-generation quantum technology.

Researchers developed a device that produces a laser with the world’s shortest wavelength, a breakthrough that a Nobel laureate expects will lead to a sea change in manufacturing around the world.

Japan will aim to develop full-fledged quantum computers for a broad range of uses by around 2039, Nikkei has learned, part of Tokyo's first strategy for catching up with the U.S. and China in the race to achieve ultrafast processing.

The race to build digital security for the quantum computing era has begun as the U.S. and China lead state-backed efforts, with Japan also joining the foray by enlisting the help of the private sector.

Nippon Telegraph and Telephone, NASA, Stanford University and other institutions have agreed to join in developing a quantum computing system that can compete against the quantum machines that Google and IBM are working on.
