• Abstract: Micro-objects levitated in a vacuum are an exciting platform for precision sensing due to their low dissipation motion and the potential for control at the quantum level. Arrays of such sensors would allow noise cancellation, directionality, increased sensitivity and in the quantum regime the potential to exploit correlation and entanglement. We use neuromorphic detection via a single event-based camera to record the motion of an array of levitated microspheres. We present a truly scalable method for arbitrary multiparticle control by implementing real-time feedback to cool the motion of three objects simultaneously, the first demonstration of neuromorphic sensing for real-time control at the microscale.

  Microwave or radio-frequency driving poses a significant limitation for miniaturization, energy-efficiency and non-invasiveness of quantum sensors. We overcome this limitation by demonstrating a purely optical approach to coherent quantum sensing. Our results pave the way for highly compact quantum sensors to be employed for magnetometry or gyroscopy applications.

  We experimentally investigate individual spin dynamics in a two-dimensional ensemble of electron spins on the surface of a diamond crystal. We show that this anomalously slow relaxation rate is due to the presence of strong dynamical disorder. Our work paves the way towards microscopic study and control of quantum thermalization in strongly interacting disordered spin ensembles.

  We introduce a new technique to model and eliminate dipole moment interactions limiting the performance of sensors employing levitated objects. As a demonstration, this is applied to the search for unknown charges of a magnitude much below that of an electron. As a by-product of the technique, the electromagnetic properties of the levitated objects can also be measured on an individual basis.

  Tests of quantum mechanics on a macroscopic scale require extreme control over mechanical motion and its decoherence.

We cool its center-of-mass motion by measurement-based feedback to an average occupancy of 0.65 motional quanta, corresponding to a state purity of 43%.

  Defects in solid state materials provide an ideal platform for quantum sensing. Control of such an ensemble is challenging due to the spatial variation in both the defect energy levels and in any control field across a macroscopic sample. We experimentally demonstrate that we can overcome these challenges using Floquet theory and optimal control optimization methods.

We show that this fast loop protocol can be used to enhance force sensing as well as to dramatically boost the entangling rate of two weakly interacting nanoparticles.
