Quantum-state engineering with optically-trapped neutral atoms — •Vladimir M. Stojanovic, Gernot Alber, Thorsten Haase, and Sascha H. Hauck — Institut für Angewandte Physik, Technical University of Darmstadt, Germany

Recent years have seen tremendous experimental progress in the realm of optically-trapped neutral atoms. In this talk, three theoretical proposals for quantum-state engineering in this type of systems will be presented. It will first be demonstrated that a deterministic conversion of a three-qubit W state into its Greenberger-Horne-Zeilinger counterpart can efficiently be carried out in the Rydberg-blockade regime of neutral-atom systems using a dynamical-symmetry-based approach. It will then be shown that a W-type entanglement can be engineered in arrays of neutral atoms with Rydberg-dressed resonant dipole-dipole interaction. Finally, a time-efficient control scheme for coherent single-atom transport in moving optical lattices (optical conveyor belts and double-well lattices) -- based on the enhanced shortcuts-to-adiabaticity approach -- will be described.
