纳米级粒子“量子挤压”首次实现

Core Insights - The research team from the University of Tokyo has achieved "quantum squeezing" of nanoparticles, reducing the uncertainty of particle motion below the zero-point fluctuations of quantum mechanics, which opens new pathways for fundamental physics research and advances technologies like high-precision sensing, autonomous driving, and navigation without GPS signals [1][2]. Group 1: Quantum Mechanics and Research Findings - The study demonstrates that quantum mechanics, which governs the micro-world, can be extended to the nanoscale, overcoming significant experimental challenges [1][2]. - The team utilized glass-made nanoparticles suspended in a vacuum and cooled to their lowest energy state to minimize uncertainty, successfully proving quantum squeezing by achieving a narrower speed distribution than the lowest energy state [2]. Group 2: Implications for Technology Development - This breakthrough provides a platform for addressing fundamental scientific challenges and developing revolutionary technologies, particularly in navigation systems that can enhance positioning accuracy and reliability without external signals [3]. - The advancements in precision measurement could significantly improve the sensitivity of atomic clocks, gravimeters, and magnetic field sensors, facilitating research in fundamental physical constants, dark matter, and early universe studies [3]. - The findings also hold potential applications in materials science and biomedicine, supporting the development of new sensors, single-molecule detection technologies, and targeted drug delivery systems [3].
