Recent experiments have demonstrated several electron sources that can controllably inject single or few particles into an electric circuit. This is a novel field of research that is at the very forefront of current investigations of quantum coherent electron transport in low temperature, on-chip electron transport. Experimentally the domain requires mastery of high-frequency measurements and theoretically it represents a push into largely unexplored dynamic electron transport theory. Different sources which are currently under investigation are emitters based on quantum pumps, mesoscopic capacitors or trains of Lorentzian pulses applied to a sample. Of interest is the full quantum statistics of the emitters which permits to assess their fidelity. The advent of single particle emitters opens unprecedented control in the generation and manipulation of quantum coherent few electron states. The generation of two-particle states has recently been successfully demonstrated. For such coherent multiparticle states the synchronization of single particle emitters becomes important as well as the coherence of the emitted states. The workshop is to present some of the key experimental and theoretical advances in this young field.
