Conditional dynamics induced by new configurations for Rydberg dipole-dipole interactions

We suggest a way to use strong Rydberg dipole-dipole interactions in order to induce nontrivial conditional dynamics in individual-atom systems and mesoscopic ensembles. Contrary to previous works, we suggest exciting atoms into different Rydberg states, which results in a potentially richer dynamical behavior. Specifically, we investigate systems of individual hydrogenlike atoms or mesoscopic ensembles excited into high-lying hydrogenlike s, p, or d states, and show how to perform three-qubit conditional dynamics on the information they contain through a proper use of dipole-dipole-interaction-induced energy shifts.
