    Abstract: The present invention relates to a nanodrone, a method of operating a nanodrone, and a system for operating a nanodrone. The nanodrone comprises a substrate extending perpendicular to a normal direction and two or more nanoantennas arranged on and/or in the substrate. Each of the two or more nanoantennas exhibits an optically addressable resonance at a respective resonance wavelength. The two or more nanoantennas comprise a first nanoantenna and a second nanoantenna, each being configured to scatter circularly polarized light at the respective resonance wavelength that is incident on the nanoantenna along the normal direction such that photons of the scattered light have a mean wavevector (I) and (II) in a plane perpendicular to the normal direction for left- and right-circularly polarized light, respectively, with i=1 for the first nanoantenna and i=2 for the second nanoantenna. The mean wavevector (III) with ji=L or R is non-zero.
