Circular Rydberg atoms, the natural lifetime of which reaches several 10ms [1], offer the perspective to run quantum simulation over unprecedented timescales [2]. To benefit from these long times, however, makes laser-trapping of circular Rydberg atoms mandatory [3].
Here, I will present our latest experimental results regarding the laser-trapping of circular Rydberg atoms in a regular array of hollow optical tweezers. Laser-cooled Rubidium atoms are initially trapped in an array of gaussian-shape optical tweezers and are then promoted to the n=52 circular Rydberg levels, while being transferred into bottle optical beams, that trap the circular Rydberg atoms through a ponderomotive force. We observe and characterize the traps by transferring back the atoms to their ground state and imaging them in the initial optical tweezers. Our results open a new route for quantum technologies with Rydberg atoms, allowing one to exploit the unique properties of the circular levels.
