A Reconfigurable Optical Tweezer Array of Fully Quantum State Controlled Ultracold Dipolar Molecules

Ultracold dipolar molecules represent a promising platform for near-term quantum information and simulation experiments, by virtue of their strong, long-range dipolar interactions and ther long-lived ground states, which can be used to robustly encode quantum information. In this talk, I will discuss our preparation of an optical tweezer array of single NaCs molecules, starting from arrays of laser-cooled Na and Cs atoms. Using adiabatic assembly of the molecules followed by microwave control of their rotation, we achieve full control over the rovibrational and hyperfine degrees of freedom of the molecule. With full control of these single molecules achieved, we are now working towards controlling dipole-dipole interactions between them and using the interaction to engineer entangling quantum gates between molecular qubits. I will further discuss our strategy to generate densely filled arrays of molecules through dynamic reconfiguration of the tweezer array.
