Probing gravitational interaction between milligram optomechanical oscillators operating in the quantum regime
M. Bonaldi, A. Borrielli, G. Di Giuseppe +12
We present an ongoing optomechanical experiment aimed at detecting gravitational interaction between milligram-scale oscillators, and exploring its interplay with quantum mechanics…
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…
Large amplitude mechanical coherent states and detection of weak nonlinearities in cavity optomechanics
Wenlin Li, Paolo Piergentili, Francesco Marzioni +9
The generation of large-amplitude coherent states of a massive mechanical resonator, and their quantum-limited detection represent useful tools for quantum sensing and for testing…
Mechanical characterization of a membrane with an on-chip loss shield in a cryogenic environment
Francesco Marzioni, Riccardo Natali, Michele Bonaldi +9
The quantum transduction of an rf/microwave signal to the optical domain, and vice versa, paves the way for technologies that exploit the advantages of each domain to perform quant…
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…
