Quantum Squeezing Applied to Nanoparticle for the First Time

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

This achievement was made possible by levitating the particle and rapidly varying its oscillation frequency, shedding light on the classical-quantum transition for small objects.

According to the researchers, this breakthrough could lead to improvements in quantum sensors and a better understanding of how small particles transition between classical and quantum behaviors.

Oscillating objects with diameters smaller than a few microns have various applications in quantum technology, including optical clocks, superconducting devices, and quantum sensors.

These objects are affected by Heisenberg’s uncertainty principle, which limits the precision of simultaneous measurements of position and momentum in quantum objects.

Could allow us to better understand how very small particles transition between classical and quantum behaviours.
