Controllable Permanent Dipoles in Rydberg Atoms

Rydberg interactions play a critical role in quantum information technologies [1-14], offering long-range, switchable interactions via coherent laser excitation. While these interactions are typically weaker than those in ion-based systems, they allow for flexible, on-demand control. To enable all-to-all connectivity in a scalable static atomic lattice quantum processor, extending the range of Rydberg interactions is essential. This talk introduces innovative methods to excite engineered Rydberg states with permanent dipole moments. By manipulating the electron cloud configurations, we demonstrate enhanced dipole-dipole interactions and explore the tunable parameters that enable dynamic control over dipole strength. These advancements provide a promising pathway for stronger, more flexible Rydberg interactions, facilitating robust quantum processing in static atomic lattices.
