Semiconductor nanowire-superconductor hybrid systems provide a promising platform for hosting unpaired Majorana fermions to realize topological qubits. Starting from the basics of quantum transport theory, and adapting it to understand quantum transport in normal superconductor junctions, we show in detail how the recently-observed oscillations in the critical supercurrent with an axial magnetic field arise from the interference of orbital angular momentum modes in the nanowire.
