How Tiny Magnetic Waves Could Power Pocket‑Sized Quantum Computers

Researchers at the University of Vienna have turned a once‑dismissed phenomenon—tiny magnetic ripples called magnons—into a promising way to carry quantum information. By tweaking the way these waves interact with their surroundings, the team stretched their lifespan from a few hundred nanoseconds to an impressive 18 microseconds, a boost of almost 100 times. This longer‑lived state means magnons can now hold quantum data long enough to be useful in real‑world devices. The breakthrough also revealed that the main obstacle isn’t a fundamental law of physics but the purity of the material the magnons travel through. In other words, cleaner, higher‑quality crystals could push the performance even further without needing brand‑new physics tricks. Why does this matter? Quantum computers rely on delicate quantum bits, or qubits, that are notoriously hard to keep stable. Magnons offer a way to move and store quantum information without the heat and electrical noise that plague other approaches. With magnons now stable enough, engineers can envision quantum processors that fit on a coin‑sized chip, opening the door to portable, affordable quantum technology. Future progress will likely come from better manufacturing techniques, making the dream of tiny, powerful quantum computers a realistic goal.

Huawei Unveils ‘Tao Law’: A New Roadmap for Computing Power Beyond Moore’s Law

On May 25, Huawei’s semiconductor chief Tingpo He announced the company’s first‑ever “Tao (τ) Law,” a theory that shifts the focus of chip development from shrinking transistors to cutting system latency and “miniaturizing time.” A revised version of the paper, posted on the ChinaXiv pre‑print platform on July 3, adds detailed calculations and a clear roadmap, turning the concept into a measurable technical framework. The Tao Law proposes that future performance gains will come from advanced packaging, chiplet integration, 2.5 D fan‑out, micro‑bump and hybrid‑bonding technologies, rather than traditional process scaling. Huawei’s Ascend AI accelerator line illustrates this vision: the Ascend 910C (2025), Ascend 950 (2026) and the upcoming Ascend 990 (around 2030) will rely on mature chiplet designs and introduce LogicFolding and later 3D‑Folding to boost AI compute. Huawei says its ecosystem already includes more than four million developers, positioning the company to embed AI power across industries through a “chip + system + ecosystem” approach. While the theory still needs engineering validation and industry adoption, experts see it as a potential cornerstone for the post‑Moore era, guiding China’s semiconductor strategy over the next decade.

China’s Bold Leap Toward Becoming a Global Science Power by 2035

China is racing to become a world‑leading science and technology power by 2035. Recent breakthroughs show the country moving from describing and preserving knowledge to creating it. Highlights include a quantum computer that can process a trillion times faster than today’s top supercomputer, a “artificial sun” that achieved 100 million‑degree fusion for over a second, and a deep‑sea probe that found abundant hydrogen at 10,000 metres, hinting at new energy sources. In space, China’s Tianwen‑1 rover detected water‑bearing minerals on Mars, and plans are set for a Mars‑sample‑return mission (Tianwen‑3) by 2031, as well as a near‑complete lunar research station and a manned lunar landing. The new spallation neutron source in Guangdong will act as a “super microscope” for extreme‑condition research, while Tsinghua University linked computing power across 4,000 km to train a massive AI model. Institutional reforms—such as the Central Science and Technology Commission—and a surge in R&D spending (up to 3.9 trillion yuan, the world’s second‑largest) are fueling these advances. Together, these efforts aim to turn frontier discoveries into everyday technologies, from 5G‑enabled factories to a million‑kilowatt “water‑light” power plant, reshaping China’s economy and its role on the global stage.

Breakthrough in Offshore Wind Power: New DC Converter Hits 98% Efficiency

A research team at the Institute of Electrical Engineering, Chinese Academy of Sciences, has unveiled a game‑changing DC‑to‑DC converter that could dramatically boost the performance of offshore wind farms. Traditional offshore wind systems lose power through long cables and complex conversion steps. The new device, a 500 kW, 5 kV, 5 kHz three‑level resonant converter, lifts the low‑voltage DC from wind turbines to a medium‑voltage level with far fewer losses. By building a detailed model of where energy is wasted—inside semiconductor switches, high‑frequency transformers, and rectifiers—the engineers identified a “check‑mark” loss pattern and introduced a novel “loss reconstruction” control strategy. This approach dynamically adjusts frequency and pulse‑width settings across the power range, suppressing the dominant loss at any given moment. The result is a peak efficiency of 98.1 % and a high‑efficiency band (above 97.8 %) that is more than 30 % wider than with conventional methods. The compact, high‑power design means fewer modules, smaller equipment footprints, and simpler control, translating to lower costs, higher safety, and greater reliability for offshore wind collections. The technology also promises benefits for large solar farms, energy‑storage installations, distributed generation, and even data‑center power supplies.
