A team proposes topological Josephson trijunctions, three-arm superconducting junctions on a semiconductor nanowire, as a platform to generate and steer Majorana quasiparticles. The three-way geometry would allow a pair of Majoranas to be created at a branching point and the supercurrent to travel along distinct paths, something two-terminal junctions cannot achieve.
