- Abstract summary: We introduce a new trapping concept for ultracold atoms in optical tweezers based on micrometer-scale lenses that are 3D printed onto the tip of standard optical fibers.
In an exploratory experiment, we have established the vacuum compatibility and robustness of the structures, and successfully formed a magneto-optical trap for ultracold atoms in their immediate vicinity.

- Abstract: Trapping of single ultracold atoms is an important tool for applications
ranging from quantum computation and communication to sensing. However, most
experimental setups, while very precise and versatile, can only be operated in
specialized laboratory environments due to their large size, complexity and
high cost. Here, we introduce a new trapping concept for ultracold atoms in
optical tweezers based on micrometer-scale lenses that are 3D printed onto the
tip of standard optical fibers. The unique properties of these lenses make them
suitable for both trapping individual atoms and capturing their fluorescence
with high efficiency. In an exploratory experiment, we have established the
vacuum compatibility and robustness of the structures, and successfully formed
a magneto-optical trap for ultracold atoms in their immediate vicinity. This
makes them promising components for portable atomic quantum devices.

Microwave or radio-frequency driving poses a significant limitation for miniaturization, energy-efficiency and non-invasiveness of quantum sensors.
We overcome this limitation by demonstrating a purely optical approach to coherent quantum sensing.

We report trapping of single ultracold atom in an optical trap that can be continuously tuned from a standard Airy focus to a subwavelength hotspot smaller than the usual Abbe's diffraction limit.
We argue that superoscillatory trapping and continuous potential tuning offer not only a way to generate compact and tenable ensembles of trapped atoms for quantum simulators but will also be useful in single molecule quantum chemistry.

Future quantum technology relies crucially on building quantum networks with high fidelity.
To achieve this goal, it is of utmost importance to connect single quantum systems in a way such that their emitted single-photons overlap with the highest possible degree of coherence.
Here we present an advanced manufacturing approach to accomplish this task: we combine 3D printed complex micro-optics such as hemispherical and Weierstrass solid immersion lenses.

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.
