Clifford gates are widely viewed as "free" operations in quantum computation, as they are classically simulable and naturally align with fault-tolerant architectures. The non-Clifford resources, known as magic, are the costly ingredient that enables universal computation. In this talk, I will characterize how magic is distributed in topologically ordered states. We show that string-net states with non-Abelian excitations host extensive long-range magic, whereas stabilizer (Clifford-generated) states can support only Abelian excitations. This establishes a connection between the computational power of non-Abelian anyons and the intrinsic magic content of the underlying states, providing a new resource-theoretic characterization of topological orders. This talk is based on arXiv:2605.15150.
