I plan to start this presentation with an overview of our work over the past decade on the effi- cient coupling of light and single quantum emitters. Some examples of the recent achieve- ments include single-photon communication of two individual molecules at long distances , coherent nonlinear optical interactions, where a single organic molecule act as an efficient switch for weak beams of light  and coherent coupling of a single molecule to a mode of a microcavity . The long-term goal of these projects is to establish a platform for nano- quantum-optical operations and cooperative interactions in a mesoscopic system of photons and quantum emitters [4-6]. In the second part of the talk, I will show how cryogenic single molecule microscopy and spectroscopy can provide the highest resolution in optical microscopy [7, 8], reaching three-dimensional Angstrom resolution in studying proteins.
