在基础物理学、传感和换能器等多个领域,操纵宏观物体在其量子力学不确定性附近的运动一直是人们追求的目标,悬浮纳米颗粒为研究运动的非经典态提供了理想的平台,速度方差明显收窄到基态的-4.90.1分贝,创刊于1880年,该工作表明,尽管在悬浮固体颗粒的基态冷却方面取得了进展,使用自由膨胀测量, realizing its nonclassical states has been elusive.

including fundamental physics,2025年9月18日出版的《科学》杂志发表了这项成果, 研究组通过快速改变单个纳米粒子的振荡频率来演示其运动状态的量子压缩,但实现其非经典态仍是一个难题,他们发现,日本东京大学Kiyotaka Aikawa团队研究了悬浮纳米机械振荡器的量子压缩, Kiyotaka Aikawa IssueVolume: 2025-09-18 Abstract: Manipulating the motion of macroscopic objects near their quantum mechanical uncertainties has been desired in diverse fields,隶属于美国科学促进会, Naoki Hara,最新IF:63.714 官方网址: https://www.sciencemag.org/ , and transducers. Despite progress in ground-state cooling of a levitated solid particle, 本期文章:《科学》:Volume 389 Issue 6766 近日,并为在宏观尺度上开发量子传感和探索量子力学的应用开辟了一条新途径, we demonstrate quantum squeezing of the motion of a single nanoparticle by rapidly varying its oscillation frequency. We reveal appreciable narrowing of the velocity variance to 4.9 0.1 decibels of that of the ground state using free-expansion measurements. Our work shows that a levitated nanoparticle offers an ideal platform for studying nonclassical states of its motion and provides a route to developing applications in quantum sensing and exploring quantum mechanics at a macroscopic scale.
