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.
Such oscillating objects have applications in quantum technology, including optical clocks, superconducting devices, and quantum sensors.
Heisenberg’s uncertainty principle places a limit on how precisely we can simultaneously measure the position and momentum of a quantum object.
