Abstract Following the first demonstration of a levitated nanosphere cooled to the quantum ground state in 2020 (U. Delić, et al. Science, vol. 367, p. 892, 2020), macroscopic quantum sensors are seemingly on the horizon. The nanosphere’s large mass as compared to other quantum systems enhances the susceptibility of the nanoparticle to gravitational and inertial forces. In this viewpoint, we describe the features of experiments with optically levitated nanoparticles (J. Millen, T. S. Monteiro… Expand

TLDR
Optomechanics is concerned with the use of light to control mechanical objects, and trapped mesoscopic particles are the paradigmatic system for studying nanoscale stochastic processes, and have already demonstrated their utility in state-of-the-art force sensing. Expand

Gravimetry through non-linear optomechanics
TLDR
It is theoretically shown that, in an optomechanical cavity, only the phase of the optical output needs to be measured to obtain a precise value for the gravitational acceleration with high sensitivity, showing that they could, in principle, surpass the best atomic interferometers even for low optical intensities.

Cavity opto-mechanics using an optically levitated nanosphere
TLDR
A novel approach is proposed, in which optically levitating a nano-mechanical system can greatly reduce its thermal contact, while simultaneously eliminating dissipation arising from clamping, which potentially opens the door to ground-state cooling and coherent manipulation of a single mesoscopic mechanical system or entanglement generation between spatially separate systems, even in room-temperature environments.

This work proposes to use an optically levitated diamond bead containing a nitrogen-vacancy center spin to show how the interference between spatially separated states of the center of mass of a mesoscopic harmonic oscillator can be evidenced by coupling it to a spin and performing solely spin manipulations and measurements (Ramsey interferometry).
