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…
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…
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…
