Overview of the experimental procedure to realize quantum squeezing

Caption

(Upper panel) Experimental time sequence to realize and observe quantum squeezing of a levitated nanoparticle. After cooling the center-of-mass motions, we vary the laser intensity to deform the uncertainties of the position and the velocity of a nanoparticle. We measure the uncertainties of the velocity by letting it fly for a short time.

(Lower panel) Time evolution of the uncertainties of the position and the velocity of a nanoparticle. Modulating the laser intensity deforms the uncertainties on the phase space comprising of the position and the velocity.
