(a) The sketch of the geometry we consider. Topological U-shaped Kitaev wire with a pair of MFs η A and η B is placed in contact with a QD, which is connected as well to two metallic reservoirs. The coupling of the QD to the MFs is asymmetric and is characterized by tunneling matrix elements λ A and λ B , while coupling to the metallic leads is symmetric and is characterized by the tunneling matrix element V. ε2 denotes the coupling between two MF states. (b) Equivalent auxiliary setup (Kitaev dimer) resulting from the mapping of the original system onto the system with nonlocal fermion residing in QD2. t is tunneling matrix element between the QDs 1 and 2, Δ is the binding energy of the Cooper pair delocalized between them.
