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, which could shed light on the classical-quantum transition for small objects.
Oscillating objects smaller than a few microns in diameter have applications in quantum technology, including optical clocks, superconducting devices, and quantum sensors.
These objects are affected by Heisenberg's uncertainty principle, limiting the precision of simultaneous position and momentum measurements.
Quantum squeezing could lead to improvements in quantum sensors.
