Majorana fermions in Josephson Junction

It has been theoretically demonstrated that Majorana fermions in superconducting system obey non-Abelian statistics, which is the most promising platform for topological quantum computing. The success in this search might ultimately prove essential to overcoming one of the grand challenges in the field—the synthesis of a scalable quantum computer.In this project, we aim to generate Majorana Fermions at the interface between a topological insulator and a superconductor. First, we will create bijunctions and realize phase control in Josephson Junction. The outcome of his step is to observe Fraunhofer diffraction in transportation measurement (current vs voltage measurement) . Second, we will create Y-shape trijunctions and vitrify the existence of Majorana fermions at the joints. The Majorana bound state will reveal itself as a zero-energy excitation on the tunneling spectrum, and it can be annihilated with modulating the phase selections. TO BE CONT’D
