Conceptual close-up of the Majorana nano-device

Two Majorana fermions (orange balls) are formed at the end of the nanowire. Electrons enter the nanowire from the Gold contact, and meet the Majorana fermion on the way. If the electron has the wrong energy (red ball), it is reflected back into the contact. If it has the right energy (green balls), it can go through the Majorana fermion via a special interaction.
