Recently, the combination of slow light polaritons with the stronginteractions between Rydberg atoms has emerged as a promising systemfor inducing a strong interaction between photons. Potentialapplications range from the implementation of phase gate for photonsto single-photon sources, as well as the generation of stronglycorrelated states of photons. I present our theoretical andexperimental studies of strongly interacting photons. I show thatthese interacting photons can be used to prepare exotic andnon-classical states of light. In the regime of attractiveinteractions, we identify multiple two-polariton bound states,calculate their dispersion, and study the resulting scatteringresonances. For three-polaritons, we study the influence of thethree-body force on the bound states. Finally, we propose a method ofengineering novel molecular-like interactions between polaritonsleading to self-bound clusters made out of light.
