Story summary

Researchers at the University of Tokyo achieved quantum squeezing in a levitated nanomechanical oscillator, reducing motion uncertainty below quantum limits.
Led by Mitsuyoshi Kamba and Kiyotaka Aikawa, this breakthrough enhances precision measurement and quantum technology applications.
The team trapped a glass nanoparticle in a vacuum using optical levitation, minimizing environmental disturbances.
They observed a velocity uncertainty narrower than the particle's zero-point motion, indicating a squeezed state.
This work improves sensor technologies and challenges existing understandings of quantum behavior in larger particles.
