      abstract     = {Networks of three-dimensional nanoribbons of topological
                      insulators (TI) in combination with superconducting
                      electrodes are promising building blocks for topoelectronic
                      applications and topological quantum computations. In our
                      approach, these structures are fabricated by a dedicated
                      fabrication method that uses selective-area growth in
                      combination with in-situ shadow evaporation of the
                      superconducting electrodes. On single straight TI
                      nanoribbons and TI ring structures, we have found pronounced
                      Aharonov-Bohm oscillations in magnetoresistance, indicating
                      transport via topologically protected surface states
                      [1,2,3]. In three-terminal TI nanoribbon T- and Y-junctions,
                      a dependence of the current on the in-plane magnetic field
                      has been observed, with the current in the surface states
                      being clearly steered toward a preferred output at different
                      magnetic field orientations. The origin of this steering
                      effect is interpreted in terms of orbital effects in
                      combination with spin-momentum locking [4]. In in-situ
                      prepared superconductor-topological insulator nanoribbon
                      Josephson junctions a pronounced supercurrent was observed
                      [5]. For multi-terminal TI hybrid junction the interplay of
                      the Josephson supercurrent in the different branches is
                      investigated. Here, we found a clear coupling in the
                      supercurrent between the different electrodes. Work done in
