Levitated nano-spheres of silica, optically trapped in a Fabry-Perot cavitywith a single trapping field and the electrostatic field of a charged ringelectrode, are used to infer the potential existence of dark matter particleswith infinitesimal charge. These particles are presumed to exist in bulk matteras relics of the primordial Universe. In the absence of infinitesimally chargedparticles within the chosen nano-sphere, the output light in this setup shouldbe thermal. However, if these particles do exist, the cavity's output light isexpected to be squeezed even at room temperature, and one could observeentanglement between light and the nano-sphere's center of mass.

Is there charged dark matter bound to ordinary matter? Can it produce observable quantum effects?
