Japanese researchers control five quantum bits in silicon at once, with almost no errors
Researchers at RIKEN in Japan controlled five quantum bits on a silicon chip at the same time, through one shared control line. They found the biggest source of errors and kept accuracy at around 99.9 per cent. That helps to build larger quantum computers.

Tiny holes that slow down light make a small Japanese chip for optical fibre far more efficient
Japanese researchers built a component that turns electrical signals into light, using tiny holes that slow the light down. It is 0.3 millimetres long, runs on low voltage and sends up to 200 gigabits per second. The next step: losing less light along the way.

Japan gives the green light: TSMC will make the most advanced AI chips in Kumamoto
The Japanese government has approved the new plan for TSMC's second chip factory in Kumamoto. From the end of 2028, 3-nanometre chips for AI will come off the line there, for the first time in Japan. The factory will, however, start smaller than first planned.

Small snakes on Borneo escape by doing cartwheels, with their head pointing straight ahead
Japanese researchers filmed dwarf reed snakes that roll away like a wheel when in danger. That is four times as fast as ordinary slithering. The clever part: while the body spins round, the head keeps looking steadily ahead.

Japan launches space probe that is to be the first to bring soil from a moon of Mars to Earth
The Japanese space agency JAXA has launched the probe MMX. In 2031 it is to bring at least 10 grams of soil from the Martian moon Phobos to Earth. That has never been done before, and it could explain how the moons of Mars came to be.

Honda builds a road that charges electric lorries while they drive
Honda and the Japanese construction companies Taisei and Taisei Rotec have the technology ready for a road that charges electric vehicles wirelessly while they drive. A test track follows at the end of 2026, and a trial on public roads from April 2027. Lorries come first.

AI designs new materials better when it also looks at the electrons
Researchers at the University of Tokyo taught Microsoft's AI model MatterGen to design the distribution of the electrons along with each new crystal. As a result, the model more often comes up with materials that are both stable and new.
