In this report we review the present state of the art of the control of propagating quantum
states at the single-electron level and its potential application to quantum information …

The quantum Hall (QH) effect represents a unique playground where quantum coherence of
electrons can be exploited for various applications, from metrology to quantum computation …

Fractional quantum Hall states have long been predicted to be a testing ground of fractional—
anyonic—exchange statistics. These topological states, which can have either an Abelian or …

Electron interferometry with quantum Hall (QH) edge channels in semiconductor
heterostructures can probe and harness the exchange statistics of anyonic 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 …

We analyze interference phenomena in the quantum-Hall analog of the Fabry-Pérot
interferometer, exploring the roles of the Aharonov-Bohm effect, Coulomb interactions, and …

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

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 …

The vanishing band gap of graphene has long presented challenges for making high-quality
quantum point contacts (QPCs)─ the partially transparent p–n interfaces introduced by …
