A Japanese superconducting quantum computer, designed and built with homegrown components and software, went live on July 28th at The University of Osaka’s Center for Quantum Information and Quantum Biology (QIQB). This achievement signifies Japan's technological prowess in quantum computing, demonstrating the nation's capacity to design, manufacture, and integrate a complete quantum system. Visitors to Expo 2025, Osaka, Kansai, Japan will have the opportunity to interact with this cutting-edge technology through a dedicated exhibit.
Implementing co-driving techniques, like the use of intelligent speed controls to mitigate congestion at traffic lights, can significantly reduce intersection carbon dioxide emissions without impacting traffic throughput or safety, according to new MIT research.
A machine learning method developed by researchers from Institute of Science Tokyo, the Institute of Statistical Mathematics, and other institutions accurately predicts liquid crystallinity of polymers with 96% accuracy. They screened over 115,000 polyimides and selected six candidates with a high probability of exhibiting liquid crystallinity. Upon successful synthesis and experimental analyses, these liquid crystalline polyimides demonstrated thermal conductivities up to 1.26 W m⁻1 K⁻1, accelerating the discovery of efficient thermal materials for next-generation electronics.
The quantum metric—a key measure of the quantum distance in solid-state materials—helps determine the electronic properties of solids, such as transport phenomena. While scientists have measured the quantum metric directly in artificial systems, its determination in solids has proven challenging. Recently, researchers from Yonsei University have obtained this quantity using photoemission measurements in black phosphorus, furthering theoretical as well as experimental quantum physics.
Research shows that while connections between innovations speed discovery, they also sharply increase the risk of total system collapse – with the sweet spot for sustainable innovation proving surprisingly narrow.
