The edge channels of the quantum Hall effect provide one dimensional chiral and ballistic
wires along which electrons can be guided in an optics‐like setup. Electronic propagation …

In the last decade, graphene has become an exciting platform for electron optical
experiments, in some aspects superior to conventional two-dimensional electron gases …

We have realized a quantum optics like Hanbury Brown–Twiss (HBT) experiment by
partitioning, on an electronic beam splitter, single elementary electronic excitations …

We investigate the energy exchanges along an electronic quantum channel realized in the
integer quantum Hall regime at a filling factor of ν L= 2. One of the two edge channels is …

Coulomb interaction has a striking effect on electronic propagation in one-dimensional
conductors. The interaction of an elementary excitation with neighbouring conductors …

Coulomb interactions have a major role in one-dimensional electronic transport. They
modify the nature of the elementary excitations from Landau quasiparticles in higher …

Quantum Hall edge channels at integer filling factor provide a unique test bench to
understand the decoherence and relaxation of single-electron excitations in a ballistic …

In analogy with quantum optics, short-time correlations of the current fluctuations are
measured and used to assess the quality of the single-particle emission of a recently …

We propose a quantum tomography protocol to measure single-electron coherence in
quantum Hall edge channels, and therefore access for the first time the wavefunction of …

The chiral edge channels in the quantum Hall regime are considered ideal ballistic quantum
channels, and have quantum information processing potentialities. Here, we demonstrate …
