In recent years, neutral atoms have emerged as one of the most promising platforms for quantum computing and quantum simulation, characterised by scalability, large coherence times, high-fidelity single atom control as well as engineerable, strong, long-range interactions. In our project we use the alkaline-earth-like element ytterbium, whose fermionic isotope 171Yb features a rich level structure that allows for sophisticated qubit schemes including midcircuit read-out, advanced error correction, and optical trapping and manipulation of Rydberg states. Here, we introduce our experimental setup and present our current progress towards building a neutral-atom quantum simulator including characterisation measurements of tweezer loading, imaging, and qubit manipulation. We further present efforts to overcome known limitations of current quantum computation and simulation platforms, like arbitrary single atom addressing techniques, efficient suppression of servo induced laser noise for highest fidelity excitation schemes, and fast spatial light modulation techniques for scalable sorting algorithms.
