Multifunctional Metalens for Trapping and Characterizing Single Atoms
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, a quarter‐wave plate, and a polarizer for trapping and characterizing single Rubidium atoms. The metalens simultaneously focuses a trapping beam at 852 nm and collects single‐photon fluorescence at 780 nm. A strong dependence of the trapping lifetime is observed on an external bias magnetic field, suggests a complex interplay between the circularly polarized trapping light and the atom's internal states. This work showcases the potential of metasurfaces in realizing compact and integrated quantum systems based on cold atoms, opening up new possibilities for studying quantum control and manipulation at the nanoscale.
