Abstract Precise control and manipulation of neutral atoms are essential for quantum technologies but largely dependent on conventional bulky optical setups. Here, a multifunctional metalens that integrates an achromatic lens with large numerical aperture is demonstrated, quarter‐wave plate, polarizer trapping characterizing single Rubidium atoms. The simultaneously focuses beam at 852 nm collects single‐photon fluorescence 780 nm. A strong dependence the lifetime observed external bias magnetic field, suggests complex interplay between circularly polarized light atom's internal states. This work showcases potential metasurfaces in realizing compact integrated systems based cold atoms, opening up new possibilities studying nanoscale.
