Nonlinear spectroscopy has evolved into an indispensable tool to probe non-equilibrium dynamics of complex quantum systems. Typically, the interpretation of these signals suffers from the enormous number of free parameters in the underlying Hamiltonians of the system and its coupling to the environment. It is highly desirable to develop new tools to extract further information from those systems. We will discuss the possibility of exploiting strong correlations of entangled light to manipulate nonlinear spectra of complex quantum systems such as photosynthetic complexes. Exciton transport can be suppressed, and two-exciton states can be selectively excited.
