Coherent control concepts using shaped femtosecond laser pulses have originally been developed for controlling the dynamics of molecular systems, and coherent two-dimensional spectroscopy provides insight into molecular electronic couplings. Recently, these principles have been extended to the realm of nano-optics. This adds new degrees of freedom through the control of spatial properties of electromagnetic near-fields in the vicinity of nanostructures. It is now possible to manipulate spatial-temporal and transport phenomena as well as to measure electronic coherences, both on a subdiffraction length scale. This talk provides a comparison between molecular and plasmonic implementations of coherent control and coherent multidimensional spectroscopies, discussing analogies and differences and showing exemplary realizations.
