Optical squeezing mediated by levitated oscillators at their quantum ground state
A. Pontin, Q. Deplano, F. Marino +1
We demonstrate optical squeezing below the shot-noise level generated through the interaction of an optical cavity field with two center-of-mass modes of a levitated nanoparticle,…
Stationary entanglement of a levitated oscillator with an optical field
Q. Deplano, A. Pontin, F. Marino +1
Stationary entanglement between the motion of macroscopic objects and light is a long-standing goal of quantum optomechanics, with implications for both fundamental tests of quantu…
Strong coupling and dark modes in the motion of a pair of levitated nanoparticles
Antonio Pontin, Quentin Deplano, Andrea Ranfagni +2
We experimentally investigate a system composed of two levitating nanospheres whose motions are indirectly coupled via coherent scattering in a single optical cavity mode. The nano…
High purity two-dimensional levitated mechanical oscillator
Q. Deplano, A. Pontin, A. Ranfagni +2
In recent years, levitated optomechanics has delivered on the promise of reaching the motional quantum ground state. An important next milestone of the field would be the generatio…
