A central Japanese town wants to limit smartphone use for all its 69,000 residents to two hours a day, in a move that has sparked intense debate on device addiction. From a report: The proposal, believed to be the first of its kind in Japan, is currently being debated by lawmakers after being submitted by Toyoake municipal government in Aichi earlier this week. Toyoake's mayor said the proposal -- which only applies outside of work and study -- would not be strictly enforced, but rather was meant to "encourage" residents to better manage their screen time. There will be no penalties for breaking the rule, which will be passed in October if approved by lawmakers. "The two hour limit... is merely a guideline... to encourage citizens," Toyoake Mayor Masafumi Koki said in a statement. "This does not mean the city will limit its residents' rights or impose duties," he said.

Japan has launched its first entirely homegrown quantum computer, built with domestic superconducting qubits and components, and running on the country's own open-source software toolchain, OQTOPUS. "The system is now ready to take on workloads from its base at the University of Osaka's Center for Quantum Information and Quantum Biology (QIQB)," reports LiveScience. From the report: The system uses a quantum chip with superconducting qubits -- quantum bits derived from metals that exhibit zero electrical resistance when cooled to temperatures close to absolute zero (minus 459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius). The quantum processing unit (QPU) was developed at the Japanese research institute RIKEN. Other components that make up the "chandelier" -- the main body of the quantum computer -- include the chip package, delivered by Seiken, the magnetic shield, infrared filters, bandpass filters, a low-noise amplifier and various cables. These are all housed in a dilution refrigerator (a specialized cryogenic device that cools the quantum computing components) to allow for those extremely low temperatures. It also comes alongside a pulse tube refrigerator (which again cools various components in use), controllers and a low-noise power source. OQTOPUS, meanwhile, is a collection of open-source tools that include everything required to run quantum programs. It includes the core engine and cloud module, as well as graphical user interface (GUI) elements, and is designed to be built on top of a QPU and quantum control hardware.

A Japanese government survey found 26.7% of people in Japan used generative AI during fiscal 2024, which ended in March. The figure tripled from the previous year but remained far behind China's 81.2% and the United States' 68.8%. People in their 20s led Japanese adoption at 44.7%, followed by those in their 40s and 30s. Among companies, 49.7% of Japanese firms planned to use generative AI, compared to more than 80% of companies in China and the US.
