The first strategy aims for mesoscopic ensemble qubits in a lattice of ~5 {\\mu}m period, so that qubits can be individually addressed and interactions can be mediated by Rydberg excitations. The second strategy aims for direct quantum simulators using sub-optical lattices of ~100 nm period. These would allow the realization of condensed matter inspired quantum many-body systems, such as Hubbard models in new pa","authors_text":"A. Tauschinsky, N.J. van Druten, R.J.C. Spreeuw, V.Y.F.
