MIT and NY CREATES have developed a way to fabricate transparent, flexible photonic integrated circuits across entire 300 mm wafers using existing semiconductor manufacturing equipment. The technique peels off thin waveguide films only a few micrometers thick, but challenges such as integrating active components remain before practical use.
A quantum router experiment using 10 qubits on China's superconducting quantum processor 'Wukong' recorded a single-unit transmission efficiency of 98%. But fidelity dropped to the 82% range in a two-layer network, and the paper itself acknowledges that the chip's structure caps scalability at five layers.
PCB manufacturing costs have risen by up to 50%, far outpacing the average 3% retail price adjustment made in August. Simultaneous shortages of copper, glass cloth, and capacitors driven by AI server demand form the structural backdrop, and pressure for further Q4 price hikes is building.
Bloomberg reports that DeepSeek plans to deploy at least 160,000 Huawei Ascend 950DT chips at a 1GW-class data center in Inner Mongolia. The chips will be used for inference only; training remains on NVIDIA. The 160,000 figure represents roughly 30% of Huawei's published cluster configuration, with component supply—not compute capacity—constraining delivery.
China's NAURA presented a SiGe/Si selective etching technology for 3D DRAM at CSTIC 2026, claiming over 500x selectivity at 64 layers—but the equipment model, throughput, and CXMT adoption remain undisclosed and unverified.
Anthropic has released a reference implementation for e-commerce AI agents. While the design excludes payment processing and locks write operations behind two-stage human approval, questions remain about adoption barriers like dynamic pricing and liability for fraudulent orders.
Tokyo University of Agriculture and Technology and Rohm have developed a polarization-independent metalens just 51 micrometers thick. The device suppresses beam divergence from a compact resonant tunneling diode source operating at 0.312 terahertz, demonstrating wavefront control that boosts radiation directivity by a factor of 3.1.
An examination of the alleged "Project Hefei," reportedly drawn up during CXMT's founding period, using South Korean prosecutors' documents and CXMT's official corporate timeline. It lays out the gap between the technology-acquisition plan and actual trial production and mass production, and clarifies that this evidence has not yet been confirmed by a court.
A closer look at the estimated value of rare earths in US coal ash, broken down by element. Drawing on recent Gulf Coast research and Australian extraction trials, this piece examines why chemical recycling, residue disposal, and securing refining partners determine whether the effort pays off.
An MIT research team has published a theoretical design for a superconducting 'arm qubit' that separates information storage from external coupling. Using a quarton coupler, their simulations predict a gate error rate of 8.6×10⁻⁵, surpassing existing experimental results—though building an actual device and verifying material losses remain future work.
