Story summary

Researchers at the University of Tokyo achieved quantum squeezing in a levitated nanomechanical oscillator, reducing motion uncertainty beyond quantum zero-point fluctuations.
This advancement, led by Mitsuyoshi Kamba and Kiyotaka Aikawa, could enhance precision measurement and benefit quantum technologies like autonomous navigation.
The team used optical levitation to isolate a glass nanoparticle in a vacuum, minimizing environmental noise for quantum state measurement.
They recorded a velocity uncertainty narrower than zero-point motion, linking quantum and classical systems.
Their findings may improve sensors in GPS-denied environments and enhance signal-to-noise ratios across applications.
