- Abstract summary: In this work, we demonstrate that an efficient dielectric metasurface lens can be used to trap and image single neutral atoms with a long working distance from the lens of 3 mm.
We characterize the high-numerical-aperture optical tweezers using the trapped atoms and compare with numerical computations of the metasurface lens performance.

- Abstract: Optical metasurfaces of subwavelength pillars have provided new capabilities
for the versatile definition of the amplitude, phase, and polarization of
light. In this work, we demonstrate that an efficient dielectric metasurface
lens can be used to trap and image single neutral atoms with a long working
distance from the lens of 3 mm. We characterize the high-numerical-aperture
optical tweezers using the trapped atoms and compare with numerical
computations of the metasurface lens performance. We predict that future
metasurfaces for atom trapping will be able to leverage multiple ongoing
developments in metasurface design and enable multifunctional control in
complex quantum information experiments with neutral-atoms arrays.

We introduce a single-photon detector design operating in the microwave domain based on a weakly nonlinear metamaterial.
We show that the single-photon detection fidelity increases with the length of the metamaterial to approach one at experimentally realistic lengths.
In stark contrast to conventional photon detectors operating in the optical domain, the photon is not destroyed by the detection and the photon wavepacket is minimally disturbed.
