| Resonant dipole-dipole interactions between Rydberg atoms allow to induce their relative motion in a controlled fashion by preparing the atoms in different electronic states. This makes Rydberg aggregates promising devices for quantum transport, which can also be used to model complex biological systems. In particular, they allow for transfer of both classical (energy, momentum) and purely quantum mechanical (coherence, entanglement) quantities, as recently demonstrated by Wuster et al [PRL 105, 053004]. We show that such transport schemes in Rydberg aggregates composed of single atoms can be extended to trapped atomic clouds using dipole blockade. Further, we discuss the effects of Rydberg dressing of ground state atoms in such aggregates, which may lead to collective motion and polyatomic non-classical superposition states. |
