Cavity Quantum Electrodynamics is a central field of research in quantum optics: the basic system is represented by a single mode of a cavity interacting with a single dipole. This is of interest, for instance, in quantum information processing in order to convert stationary into flying qubits. We study the interaction between single terrylene molecules and the high-Q modes of a microsphere resonator. To date microsphere resonators offer the best possible optical properties: Q-factors up to 0.09*1010 with mode volumes of few hundreds of µm3 lead to very high Purcell factors [1,2,3] and possibility of strong coupling [4] . Terrylene molecules have shown very stable behavior at room temperature when spin-casted in ultrathin films of about 20 nm, being photostable for times as long as one day [5]. We report first results on coupling a single molecule to high-Q modes and discuss future experiments with two or more molecules.
