Circular Rydberg states for quantum many-body physics — Christian Hölzl, Muamera Basic, and •Florian Meinert — 5. Physikalisches Institut and Center for Integrated Quantum Science and Technology, Universität Stuttgart, Stuttgart, Germany

Highly excited low-L Rydberg atoms in configurable mircotrap arrays have recently proven highly versatile for studying quantum many-body spin systems with single particle control. I will report on the status of a new project pursuing to harness high-L circular Rydberg atoms for quantum simulation. When stabilized in a suitable cavity structure, circular Rydberg states promise orders of magnitude longer lifetimes compared to their low-L counterparts and thus provide an appealing potential to strongly boost coherence times in Rydberg-based interacting atom arrays. We propose a novel approach to stabilize circular Rydberg states against black-body decay in a room temperature setup combined with excellent optical access for generating flexible trap arrays.
