Schematic description of the setup. A Fermi function (red) on the left hand side represents the normal metal, while the density of states of the topological superconductor is depicted on the right hand side (purple). The density of states of a topological nanowire consists of a narrow peak at zero energy, attributed to the Majorana bound state, as well as quasiparticle energy bands for \(|\varepsilon | \ge \Delta\), where \(\Delta\) represents the superconducting gap. The central region (green) represents a single level quantum dot, which is coupled to the two leads by tunnel couplings depicted by the two barriers surrounding the dot.
