In semiconductor-superconductor hybrid structures a topological phasetransition is expected as a function of chemical potential or magnetic fieldstrength. We show that signatures of this transition can be observed innonlinear Coulomb blockade transport through a ring shaped structure. Inparticular, for a fixed electron parity of the ring, the flux periodicity ofthe neutral excitation spectrum changes from the usual h/2e periodicity to acharacteristic h/e periodicity when tuning the system from the topologicallytrivial to the nontrivial phase. We relate the h/e periodicity to the recentlypredicted 4\pi periodicity of the Josephson current across a junction formed bytwo topological superconductors.
