The NOG’s activities focus on low-dissipation oscillators, consisting of nanoparticles optically trapped in high vacuum. We aim to bring this levitated opto-mechanical platform into the harmonic oscillator quantum regime. To this end, we are investigating cooling mechanisms and protocols for preparing nonclassical states of motion that can be used to realize quantum-enhanced sensors such as accelerometers or gravimeters.

Experimental probability currents in velocity space in the velocity plane. The color maps the steady-state probability distribution in velocity. This study illustrates that an optically tweezed particle’s system is intrinsically out-of-equiibrium.
