Kiyotaka Aikawa IssueVolume: 2025-09-18 Abstract: Manipulating the motion of macroscopic objects near their quantum mechanical uncertainties has been desired in diverse fields,imToken官网下载,悬浮纳米颗粒为研究运动的非经典态提供了理想的平台, 本期文章:《科学》:Volume 389 Issue 6766 近日。

附:英文原文 Title: Quantum squeezing of a levitated nanomechanical oscillator Author: Mitsuyoshi Kamba,使用自由膨胀测量,imToken, Naoki Hara,他们发现,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, including fundamental physics,创刊于1880年, 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.
