Recent experiments on topological superconducting wires detected first signatures of Majorana fermions in hybrid superconductor-semiconductor heterostructures. These Majorana states are regarded as promising building blocks for a quantum computer. Since transport measurements are the primary tool of identification of these phases, a profound understanding of the processes involved is essential. I will give some background on the transport theory of topological superconductors and then discuss some recent work, both on the zero-bias peak in NS junctions and the 4pi-periodic Josephson effect in SNS junctions.
