“量子优势”首获实验证明
Ke Ji Ri Bao· 2025-09-28 22:55
Core Insights - An international collaborative research team from Denmark, the United States, Canada, and South Korea has experimentally demonstrated the capability of quantum technology to significantly outperform classical methods, achieving a task completion time reduction from 20 million years to just 15 minutes, thereby realizing "quantum advantage" [1][2]. Group 1: Research Findings - The research addresses a common challenge in efficiently understanding complex and noisy physical systems, where traditional methods require extensive measurements to infer system behavior, which becomes increasingly difficult for quantum systems due to measurement disturbances and exponential growth in required measurements as system size increases [1]. - The Danish technical university team introduced a unique quantum resource: entangled light, which allows for simultaneous extraction of more effective information through joint measurements, significantly reducing measurement ambiguity [2]. Group 2: Implications and Applications - The results indicate that the efficiency improvement is not due to more precise equipment but rather the inherent quantum advantage of the measurement method itself, achieved in a realistic lossy system rather than an idealized lossless environment [2]. - This breakthrough not only highlights the speed enhancement but also showcases the potential applications of quantum technology in fields such as sensing, system identification, and machine learning, paving new paths for quantum metrology and sensing [2][3]. - The transition of quantum advantage from theoretical discussions to practical demonstrations suggests a promising future for the development of high-sensitivity quantum sensors and innovative solutions in big data analysis and machine learning, significantly reducing energy consumption and time costs [3].
