- Abstract: Neutral atoms trapped in microscopic optical tweezers have emerged as a growing platform for quantum science. Achieving homogeneity over the tweezers array is an important technical requirement, and our research focuses on improving it for holographic arrays generated with a Spatial Light Modulator (SLM). We present a series of optimization methods to calculate better holograms, fueled by precise measurement schemes. These innovations enable to achieve intensity homogeneity with a relative standard deviation of 0.3 %, shape variations below 0.5 %, and positioning errors within 70 nm. Such ultra-precise holographic optical tweezers arrays allow for the most demanding applications in quantum science with atomic arrays.

We introduce a hologram design method based on the optimisation of a nonlinear cost function using a holographic phase pattern.
We confirm a spot interval of 0.952(1) $mu$m in a $5 times 5$ multispot pattern on the focal plane of a high-numerical-aperture (0.75) objective.
The proposed method is expected to advance laser fabrication, scanning laser microscopy, and cold atom physics, among other fields.

Accurate calibration of the wavefront and intensity profile of the laser beam at the SLM display is key to the high fidelity of holographic potentials.
Here, we present a new calibration technique that is faster than previous methods while maintaining the same level of accuracy.
This approach allows us to measure the wavefront at the SLM to within $lambda /170$ in 5 minutes using only 10 SLM phase patterns.

We develop a Gaussian-decomposition-assisted approach to inline holography, for single-shot, simultaneous measurements of absorption and phase-shift profiles.
The phase-angle readout is not only robust against transition saturation, but also insensitive to atom-number and optical-induced interaction-strength fluctuations.
We demonstrate single-shot 3D field sensing by measuring local light shifts to the atomic array with micrometer spatial resolution.

We investigate the application of genetic and machine learning approaches to tomographic problems.
We find that the neural network-based scheme provides a significant speed-up, that may be critical in applications requiring a characterization in real-time.
We expect these results to lay the groundwork for the optimization of tomographic approaches in more general quantum processes.

Multi-photon interference is at the heart of photonic quantum technologies.
Here, we experimentally demonstrate that detection can be implemented with a temporal resolution sufficient to interfere photons detuned on the scales necessary for cavity-based integrated photon sources.
We show how time-resolved detection of non-ideal photons can be used to improve the fidelity of an entangling operation and to mitigate the reduction of computational complexity in boson sampling experiments.
