Abstract
The present description relates to a method and a device for providing anyons that may be used for topological quantum computation. The method comprises the steps of providing a magnetic material containing at least one magnetic texture providing a superconductor containing at least one vortex; creating at least one magnetic texture-vortex pair by coupling the magnetic material to the superconductor, wherein each magnetic texture-vortex pair binds an anyon being localized at the vortex of the respective magnetic texture-vortex pair in the superconductor.
