Abstract
Embodiments relate to initializing and/or performing state preparation for an atomic object. The controller controls first manipulation sources to provide first manipulation signals and second manipulation sources to provide second manipulation signals. The first and second manipulation signals are incident on the atomic object. The atomic object has a nuclear spin greater than one half. A ground state manifold of the atomic object comprises one or more selected ground manifold states and non-selected ground manifold states. The first manipulation signals are configured to drive transitions from the non-selected ground manifold states to one or more pumped manifolds of the atomic object and suppress transitions out of the selected ground manifold states. The second manipulation signals are configured to stimulate the atomic object to decay a pumped manifold into a decayed state, wherein there is a non-zero probability that the decayed state is one of the selected ground manifold states.
