Core Insights - The research team from the University of Tokyo has achieved "quantum squeezing" of nanoscale particles, reducing their motion uncertainty below the quantum mechanical zero-point fluctuations, which opens new pathways for fundamental physics research and advancements in high-precision technologies such as sensors, autonomous driving, and navigation without GPS signals [1][2]. Group 1 - The macro physical world follows classical mechanics, while the micro world adheres to quantum mechanics, characterized by inherent uncertainty in measurement precision due to quantum fluctuations [1]. - Quantum squeezing refers to the generation of quantum states with uncertainty smaller than zero-point fluctuations, crucial for understanding natural phenomena and developing next-generation technologies influenced by quantum effects [1][2]. Group 2 - The research team utilized glass-made nanoscale particles suspended in a vacuum and cooled to the lowest energy state to minimize uncertainty, achieving a narrower speed distribution than the minimum energy state under optimal release timing [2]. - The achievement of quantum squeezing was the result of overcoming numerous technical challenges over several years, including additional fluctuations from particle suspension and minor disturbances in the experimental environment [2]. - The suspended nanoscale particle system is highly sensitive to environmental changes, making it an ideal platform for studying the transition between quantum and classical mechanics, and laying the groundwork for the development of new quantum devices [2].
