摘要: Although interesting per se, decoherence and relaxation of single-electron excitations induced by strong effective screened Coulomb interactions in Quantum Hall edge channels are an important challenge for the applications electron quantum optics information sensing. In this paper, we study intrinsic within ideal channel with long-range to determine influence material sample properties. We find that weak-coupling materials characterized a high velocity hot-electron may offer perspectives limiting due electron/electron interactions. discuss quantitively how extrinsic coupling channel's electromagnetic environment can be efficiently inhibited specifically designed samples at $\ensuremath{\nu}=2$ one closed propose realistic geometry testing control Hong-Ou-Mandel experiment.
