A research group in Japan led by Professor YAMAMOTO Takashi, Deputy Director, Center for Quantum Information and Quantum Biology / Graduate School of Engineering Science, the University of Osaka, in collaboration with the National Institute of Information and Communications Technology (NICT) and Hamamatsu Photonics K.K., has successfully demonstrated a world-record 10-channel multiplexed quantum photonic interface based on an integrated waveguide array, a key technology for optically interconnecting multiple quantum computers.

The next generation of microelectronics relies on radical improvements in transistor switching performance to advance computing power. However, conventional semiconductor technology has hit a physical limit known as the "Boltzmann tyranny," which restricts the energy efficiency of traditional transistors and stalls progress in high-performance electronics. To address this key bottleneck, a research team at The Hong Kong Polytechnic University (PolyU) has engineered a novel tunnelling field-effect transistor (TFET) utilising two-dimensional (2D) nanomaterials. The breakthrough brings this long-awaited experimental technology closer to commercial reality, offering a fundamental building block for energy-efficient computing and next-generation artificial intelligence (AI) chips.

By combining two complementary clues—camera geometry and visual appearance—researchers at Institute of Science Tokyo, Japan, developed a new approach for preserving identities across multiple cameras. The method uses epipolar geometry to identify spatially consistent candidate matches and appearance similarity to distinguish between possible identities. The approach can be integrated with existing single-camera tracking systems without requiring environment-specific retraining.

An analysis of 500 S&P 500 companies revealed that traditional sector labels only partially explain firms’ financial structures. Machine-learning models predicted sectors from accounting ratios, achieving a maximum validation accuracy of 49.3%. However, an unsupervised analysis identified nine financially interpretable groups that crossed sector boundaries. This suggests that, when comparing profitability, leverage, liquidity, and cash-generation patterns, accounting-based peer groups can complement sectors.
