Developing a Hybrid Tweezer Array of Rydberg Atoms and Polar Molecules — •Kai Voges, Daniel Hoare, Yuchen Zhang, Qinshu Lyu, Jonas Rodewald, Ben Sauer, and Michael Tarbutt — Centre for Cold Matter, Imperial College London, UK

Hybrid tweezer arrays of atoms and molecules are a novel and versatile platform for quantum science and technology. The combination of Rydberg atoms with their large electric dipole moment and polar molecules with their rich level structure and long state coherence times makes this approach a promising candidate for quantum simulation [1] and computing [2,3].
In this talk, I present our efforts to build a hybrid tweezer array based on ultracold Rb atoms and directly laser-coolable CaF molecules. I discuss the advantages and challenges of using such a hybrid system and present our preparation procedures for the atoms and molecules. Furthermore, I show our efforts in trapping and imaging individual atoms and molecules and present our ideas for loading both species into separate tweezer arrays.
Our approach will make it possible to construct arbitrary patterns of atoms and molecules. Through the dynamic rearrangement of tweezers and the long-range interactions mediated by Rydberg atoms, this hybrid platform will be a compelling candidate for scalable quantum computing.
