Quantum Simulations: Towards EIT ground-state cooling of single trapped ions on a surface electrode trap — •Apurba Das, Deviprasath Palani, Florian Hasse, Ole Pikkemaat, Frederike Dörr, Leon Göpfert, Ulrich Warring, and Tobias Schaetz — Physikalisches Institut, University of Freiburg, Hermann-Herder-Str. 3, 79104 Freiburg i. Br.

Tailored trap configurations for individually confined ions, employing both localized and global control fields, allows us to design and fine-tune intricate quantum systems. Two-photon stimulated Raman transition are typically utilized for individual state control and the coupling of internal and external degrees of freedom within our systems. In forthcoming endeavors, the objective is to incorporate ground state cooling via electromagnetically-induced transparency. This broadband cooling method aims to efficiently cool multiple modes to deterministically prepare the system close to its motional ground state. The poster offers an overview of essential technical advancements, recent progress towards experimental quantum simulations.
