Core Viewpoint - The article discusses the strategic transformation of China's new materials industry by 2025, emphasizing a "three-dimensional war" approach that includes "fortress materials" for national security, "sovereign materials" for technological independence, and "fusion materials" for future industry definition [3]. Group 1: Fortress Materials - The development of safety dimension materials is closely tied to national core interests, focusing on absolute reliability and performance under extreme conditions rather than cost-effectiveness [5]. - A significant breakthrough in 2025 is the mass production of the fourth-generation single crystal high-temperature alloy turbine blades, which can withstand temperatures above 1200°C and have a lifespan increased by nearly 50% compared to previous generations [8][10]. - Continuous silicon carbide fibers have transitioned from laboratory preparation to stable engineering mass production, with a production capacity of hundreds of tons, marking a strategic leap in the aerospace sector [14][15]. Group 2: Sovereign Materials - Sovereign materials focus on achieving "self-control" and enhancing industrial competitiveness, particularly in strategic sectors like semiconductors and high-end manufacturing [40]. - In the semiconductor sector, the production of 12-inch silicon wafers has reached a milestone with over 500,000 monthly shipments, and significant advancements in low-oxygen high-resistivity silicon wafer technology have been made [44]. - The domestic supply ratio of 300mm semiconductor silicon wafers is expected to increase from 15% to 40% by the end of 2025, significantly reducing reliance on imports [45]. Group 3: Fusion Materials - The fusion materials dimension represents a shift towards creating new demands and defining new products, characterized by the integration of materials science with cutting-edge fields like artificial intelligence and synthetic biology [72]. - AI-driven platforms for materials research have emerged, enabling rapid property prediction and screening, significantly reducing development cycles for critical materials [74]. - The integration of intelligent materials in robotics is evolving, allowing materials to interact with their environment and make autonomous decisions, marking a shift from passive components to intelligent structures [77].

科学仪器:量子科技突破的关键支撑——访中国科学院院士俞大鹏
仪器信息网· 2025-08-25 04:07
Core Viewpoint - Quantum technology is not an abstract concept; it heavily relies on advanced scientific instruments for development, as emphasized by Professor Yu Dapeng, a leading figure in China's quantum technology field [4][6]. Group 1: Current State of Quantum Technology - China's quantum technology is experiencing differentiated development across three main areas: quantum communication, quantum computing, and quantum precision measurement [7]. - In quantum communication, China has transitioned from a follower to a leader, exemplified by the "Mozi" quantum satellite [7]. - The quantum computing sector has seen China achieve a "catching up" status, with significant advancements in superconducting and photonic quantum computing [7]. - However, in quantum precision measurement, China still lags behind the U.S. due to high precision requirements for scientific instruments [7][8]. Group 2: Challenges in Scientific Instrumentation - The development of quantum technology is constrained by the lack of advanced scientific instruments, which are crucial for breakthroughs [8]. - Key challenges in the autonomous development of scientific instruments include a weak industrial foundation, market environment issues, external technology blockades, and user perception problems [9]. - The reliance on imported high-end equipment poses risks, including high costs and supply chain vulnerabilities [8][9]. Group 3: Solutions for Innovation - Professor Yu proposes a "three-in-one" innovation system to address these challenges, focusing on talent cultivation, policy support, and optimizing the innovation ecosystem [9]. - The need for a talent cultivation system that produces professionals skilled in both quantum physics and engineering is emphasized [9]. - Establishing special funds for high-end instrument development and improving government procurement policies for domestic products are recommended [9]. Group 4: Innovations at Shenzhen International Quantum Research Institute - The Shenzhen International Quantum Research Institute has made significant strides in quantum technology, achieving national laboratory standards within five years [12]. - The institute focuses on solid-state quantum computing and has successfully developed domestic scientific instruments, including dilution refrigerators [12][13]. - Future plans include tackling high-end equipment such as transmission electron microscope aberration correctors and multi-beam lithography machines, which are vital for quantum research and semiconductor industries [13][14]. Group 5: Future Outlook and Talent Development - Quantum technology is viewed as a critical area for national competition, with confidence in achieving breakthroughs supported by government initiatives [14]. - The relationship between scientific instruments and quantum technology is highlighted as mutually beneficial, where advancements in one area drive progress in the other [14]. - Innovative approaches to talent development are suggested, including reforming evaluation systems and fostering interdisciplinary education [14].
