Strong coupling of a single quantum system to an optical resonator is a hallmark of quantum optics. It is characterized by the repeated coherent exchange of a single excitation between the emitter and the resonator. We study strong coupling of single emitters to plasmonic nanoresonantors at room temperature. We use AFM technology to position emitters within the ultrasmall subwavelength mode volumes of broadband plasmonic nanoresonantors. The goal is to achieve deterministic photon-atom interaction for quantum communication as well as the development of novel quantum optical imaging modalities.
