In recent years, neutral atoms have emerged as a promising platform for quantum computing and quantum simulation, featuring scalable and highly coherent quantum systems with high-fidelity single-atom control as well as engineerable strong long range interactions. We use the alkaline-earth-like element ytterbium, whose fermionic isotope 171Yb features a rich level structure, allowing e.g. for optical trapping and manipulation of Rydberg states, as well as metastable states, offering the realisation of sophisticated qubit schemes.
In this talk, we introduce our experimental setup, show characterisations of tweezer loading and imaging, and present our current progress towards building a neutral-atom quantum simulator. We further present efforts to overcome known limitations of current quantum computation and simulation platforms, like arbitrary atom addressing techniques and efficient suppression of servo induced laser noise for highest fidelity excitation schemes.
