The fusion of non-Abelian anyons or topological defects is a fundamental operation in measurement-only topological quantum computation.
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majorana zero modes.
Spin-orbit interaction (SOI), a relativistic effect linking the motion of an electron (orbit) with its magnetic moment (spin), is an essential ingredient for various realisations of topological superconductivity, which host Majorana zero-modes, the building blocks of topological quantum computation.
