Rydberg atoms open new perspectives for long-range correlated many-body states due to their strong van der Waals interactions. In our setup we optically excite Rydberg atoms and detect them with

submicron resolution, which allows us to measure spatial correlations of resulting ordered states.

The system sizes studied in experiment allow for high-accuracy simulation of the Rydberg Hamiltonian. Theoretical development of optimal adiabatic pulses and experimental studies can thus proceed side

by side, both profiting strongly from each other.

We will present our recent progress in detection and control of these finite Rydberg systems.
