    "abstract": "Modern techniques allow experiments on a single atom or system, with new\nphenomena and new challenges for the theoretician. We discuss what quantum\nmechanics has to say about a single system. The quantum jump approach as well\nas the role of quantum trajectories are outlined and a rather sophisticated\nexample is given.",
