Research paperTheoreticalComputational KmcExperimental CharacterizationDetecting crossed Andreev reflection in a quantum Hall interferometer with a superconducting beam splitterMaxime Jamotte, Tom Menei, Manohar Kumar, Alexander Zyuzin et al.2026·arXiv:2604.09463AbstractWe study time-domain electron interferometry in a Hong-Ou-Mandel geometry where a thin superconductor between two quantum Hall systems acts as the beam splitter. By comparing the measurable current cross correlations at the interferometer outputs with those of a normal-conducting electronic Hong-Ou-Mandel setup, we show that Andreev processes strongly affect the HOM dip. Using scattering theory and numerical tight-binding simulations for a graphene quantum Hall bar, we show that charge cross correlations can be used to experimentally detect and characterize local and crossed Andreev processes.Read more
