Majorana fermions were predicted in 1937 by Ettore Majorana in Rome. These are particles with the mysterious property that they are equal to their anti-particles. This defining property immediately implies that these 'Majoranas' have zero charge and zero energy. Ongoing searches for detecting Majoranas occur in the context of high-energy physics and dark
matter, but yet without success. Simultaneously, condensed matter theorists proposed specially designed electronics chips that can host Majoranas. The search for these Majoranas seems successful and we will present the story and experimental signatures. Interestingly it turns out that Majoranas may be key in developing a quantum computer.
