CUA Seminar – Michael Tarbutt: Could ultracold molecules be useful for quantum computing
Location:Harvard Jefferson 250

Ten Minute Talk:"Optical Trapping of a Polyatomic Molecule" by
Christian Hallas,
Harvard
Ultracold molecules are now being produced by many groups, either by atom association of or by direct laser cooling. They can be used to test fundamental physics, study quantum chemistry, simulate many-body quantum systems, and process quantum information. In my group, we are pursuing all these applications using laser-cooled CaF and YbF molecules. I will give a brief overview of our recent experiments, focussing on the study of collisions between atoms and molecules and our efforts to produce an array of molecules in tweezer traps. Then I will outline how the dipole-dipole interaction can be used for two-qubit gates in a tweezer array of molecules, and consider the strengths and weaknesses of this approach. Finally, I will present some new ideas that exploit the advantages of both molecules and Rydberg atoms, exploring whether this hybrid system could be useful for quantum computing.
