Towards coupling atomic tweezers to an optical cavity — •Stephan Roschinski, Johannes Schabbauer, Davide Natale, Giacomo Hvaring, Iris Haubold, Nicole Heider, Alexander Heiss, Marvin Holten, and Julian Léonard — Atominstitut, TU Wien, Austria

A central goal of current research is to efficiently create entangled states among an increasing number of qubits. While atomic platforms provide great scalability, they mostly rely on local interactions, for instance, collisional or Rydberg interactions. We describe the progress to build a novel platform to entangle atoms with non-local operations using photon-mediated interactions. The atoms will be trapped within individual optical tweezers which are coupled to the field of an optical cavity. Large optical access through a high-resolution microscope objective will enable us to individually address each atom and control its coupling with all-to-all connectivity. Further advantages of this platform include partial non-destructive readout and efficient multi-qubit entanglement operations. In the long term, the proposed platform provides a scalable path to studying many-body systems with programmable connectivity, as well as an efficient atom-photon interface for quantum communication applications.
