Query: Coherence and Indistinguishability of Single Electrons Emitted by
  Independent Sources   The on-demand emission of coherent and indistinguishable electrons by
independent synchronized sources is a challenging task of quantum electronics,
in particular regarding its application for quantum information processing.
Using two independent on-demand electron sources, we trigger the emission of
two single-electron wavepackets at different inputs of an electronic
beamsplitter. Whereas classical particles would be randomly partitioned by the
splitter, we observe two-particle interferences resulting from quantum
exchange. Both electrons, emitted in indistinguishable wavepackets with
synchronized arrival time on the splitter, exit in different outputs as
recorded by the low frequency current noise. The demonstration of two-electron
interference provides the possibility to manipulate coherent and
indistinguishable single-electron wavepackets in quantum conductors.
