Physicists at the University of Tokyo, Japan have successfully performed quantum mechanical squeezing on a nanoparticle.
This feat was achieved by levitating the particle and rapidly varying its oscillation frequency, shedding light on the classical-quantum transition for small objects.
Oscillating objects smaller than a few microns have applications in quantum technology, including optical clocks, superconducting devices, and quantum sensors.
These objects are affected by Heisenberg’s uncertainty principle, limiting precise measurement of position and momentum.
could allow us to better understand how very small particles transition between classical and quantum behaviours.
