  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 the first truly scalable method for multiparticle
control by implementing real-time feedback to cool the motion of three objects
simultaneously.
