Customized trap architectures for single trapped atoms with suitable local and global control fields enable us to set up and tune increasingly complex quantum systems with a high level of control. For individual state control and coupling of internal and external degrees of freedom in the system, we typically implement two-photon stimulated Raman transition. In our future work, in addition to our established control features, we want to bring ground state cooling based on electromagnetically-induced transparency to enable broadband cooling of multiple modes to deterministically prepare the system to its global ground state. This will allow us to prepare our 25Mg+ arrays for further quantum operations more efficiently. Here in this presentation, we give an overview of required technical developments, recent advancements and discuss important steps towards near-future applications.
