The advent of synthesizing controllable quantum systems has opened new avenues for exploring complex quantum phenomena that are otherwise challenging to study in traditional solid-state materials. Synthetic quantum platforms, such as ultracold atoms in optical lattices and cavities, have been pivotal in investigating a myriad of quantum phenomena and advancing quantum technologies. Notable examples include the realization of synthetic spin-orbit-coupling in ultracold atoms, which enables the exploration of topological physics using charge-neutral particles, and the observation of many-body entangled states, which are essential for quantum-enhanced sensing and computing applications.
