Physicists Apply Quantum Squeezing to a Nanoparticle

Physicists at the University of Tokyo, Japan have performed quantum mechanical squeezing on a nanoparticle for the first time.

This demonstration could shed light on the nature of the classical-quantum transition for small objects, achieved by levitating the particle and rapidly varying the frequency at which it oscillates.

Allow us to better understand how very small particles transition between classical and quantum behaviours.
Lead to improvements in quantum sensors.

Such objects are small enough to be affected by Heisenberg’s uncertainty principle, which places a limit on how precisely we can simultaneously measure the position and momentum of a quantum object.

Oscillating objects that are smaller than a few microns in diameter have applications in many areas of quantum technology, including optical clocks and superconducting devices.
