Majorana theory

Web1 dag geleden · Other topics include symmetry in quantum field theories, a relativistic 10-fold way, the homotopy theory of relativistic free fermions, and a topological spin-statistics theorem. Majorana bound states in quantum error correction. One of the causes of interest in Majorana bound states is that they could be used in quantum error correcting codes. This process is done by creating so called 'twist defects' in codes such as the toric code which carry unpaired Majorana modes.
