Scalable architecture for quantum simulation and quantum computation with more than 150 individually addressable qubits — •Dominik Schäffner, Daniel Ohl de Mello, Tilman Preuschoff, Lars Kohfahl, Jan-Niklas Schmidt, Malte Schlosser, and Gerhard Birkl — Institut für Angewandte Physik, TU Darmstadt, Schlossgartenstraße 7, 64289 Darmstadt, Germany

Efficient quantum simulation and quantum information processing requires scalable architectures that guarantee the allocation of large-scale qubit resources. In our work, we focus on the implementation of multi-site geometries based on microfabricated optical elements. This approach allows us to develop flexible, integrable and scalable configurations of multi-site focused beam traps for the storage and manipulation of single-atom qubits and their interactions [1].

We give an overview on the investigation of ⁸⁵Rb atoms in two-dimensional arrays of more than 400 individually addressable dipole traps featuring trap sizes and a tunable site-separation in the single micrometer regime. Furthermore, we experimentally demonstrate single-atom quantum registers with more than 150 occupied sites and single-site resolved addressing of single atom quantum states in a reconfigurable fashion. We will discuss progress in introducing Rydberg based interactions and present prospects of our platform for the investigation of many-body physics.
