Vison manipulation with local magnetic fields

ORAL

Abstract

Quantum spin liquids hosting non-abelian anyons have recently experienced renewed interest following the discovery of a variety of materials proximate to these quantum phases. Their anyonic excitations have potential for application to topological quantum computation, but designing logical operations with reduced poisoning requires developing protocols to faithfully create, move and read-out such quasiparticles. In this paper, we present one such protocol for manipulating Z2 fluxes (``visons'') of ferromagnetic and antiferromagnetic Kitaev models perturbed by a small uniform magnetic field. Our design employs a local driving magnetic field and can achieve high probabilities of generating and displacing flux pairs of both the Az and B phases of the model.
