We describe a framework for the design of optimal electromagnetic pulses to implement given operations on N-level quantum systems. The techniques are demonstrated in a variety of concrete examples: (i) the optical manipulation of Pr dopant ions in a YrSO4 crystal, (ii) the preparation of cluster states on coupled spin systems - where both analytical solutions in an idealised case and numerical solutions for an experimental ion trap system are obtained, and (iii) the implementation of quantum computing gates in a superconducting cavity grid architecture.
