In this video I visited Microsoft’s quantum labs to see how they are making their topological quantum computers and learn how topology helps their quantum devices avoid noise by harnessing the power of Majorana quasiparticles which are made from an exotic form of superconductivity where the electrons behave like there is a Majorana particle there which has the special properties of topology.
