The goal of making Majorana states in the lab requires bringing together very different and sometimes incompatible physical phenomena : superconductivity, magnetic field, and one-dimensional systems. The reward is high—creating and controlling the first non-Abelian anyons, exotic particles, but so is the challenge. I will show how different physical phenomena impact the creation of Majoranas. I will show how the coupling strength to the superconductor impacts the goal of creating Majoranas and how the orbital effect of magnetic field impacts the spin-orbit physics. Going further, I will show how to detect these physical phenomena using the nonlocal conductance as a bulk probe of induced superconductivity.
