Description
Hybrid tweezer arrays of molecules and atoms represent a novel and promising platform for quantum science and technology. Optical tweezers enable highly flexible and dynamic trapping configurations. With their rich internal level structures and long rotational state coherence times, molecules are well suited for storing quantum information and can serve as excellent qubits. Their interactions can be significantly enhanced by employing Rydberg atoms to mediate long-range dipole–dipole interactions. This hybrid platform therefore offers an intriguing approach to quantum simulation [1] and quantum computing [2,3].
I will present our approach and conceptual design for constructing a new apparatus for hybrid tweezer trapping of ultracold SrF molecules and Sr atoms. I discuss the advantages of the SrF+Sr species combination, as well as the associated experimental challenges. Furthermore, I outline our design for the dual-species apparatus, including the source based on a cryogenic buffer-gas cell, the magneto-optical traps, and the optical tweezer trapping region.
Our planned hybrid architecture has the potential to open new pathways toward scalable quantum technology, especially with regards to quantum computing and simulation with trapped single particles.
