protected braiding operations of ising anyons up to an overall phase on the topological state space it follows from this that majorana wire networks can be utilized as ising anyons for topologically protected quantum information processing a concrete realization of a topological quantum bus that uses the aharonov casher effect to coherently transfer quantum information between a topological qubit in a majorana wire system and a conventional semiconductor double dot qubit will now be described in detail the aharonov casher effect involves interference of particles with magnetic moment vortices moving around a line charge it may enable performance of non local measurements of charge in a region by utilizing the interference of vortices traveling through two different paths around the region for superconducting systems it is natural to try to use abrikosov vortices in this context however abrikosov vortices in s wave superconductors may have rather large mass due to the large number of subgap states localized in their cores as a result these vortices may behave classically an alternative is to use josephson vortices fluxons which arise due to phase slip events in josephson junctions their effective mass is determined by the charging and josephson energies of the junction and can be much smaller than that of abrikosov vortices allowing them to behave quantum mechanically indeed the aharonov casher effect with josephson vortices has been experimentally observed and.
