Detecting Majorana fermions is a challenging task, but recent advancements in nanotechnology have made it possible. One common method involves creating a hybrid system of a superconductor and a semiconductor nanowire. When a magnetic field is applied to such a system, zero-energy states, which are indicative of Majorana fermions, can appear at the ends of the nanowire. These zero-energy states can be detected using scanning tunneling microscopy (STM) and other advanced techniques.
