The implementation of electromagnetically induced transparency (EIT) in a cold Rydberg gas provides an attractive route towards strong photon-photon interactions and fully deterministic all-optical quantum information processing. In this brief review we discuss the underlying principles of how large single photon nonlinearities are achieved in this system and describe experimental progress to date.
