Demonstration of magic state power of $\mathbf{D}(\mathbf{S}_{3})$ anyons with two qudits

Abstract

We consider a lattice of d=6d=6 qudits that supports D(S3)\mathbf{D}(\mathbf{S}_3) non-Abelian anyons. We present a method for implementing both braiding and fusion evolutions using only the operators that create and measure anyons, without requiring additional dynamical control. This provides a minimal protocol demonstrating that D(S3)\mathbf{D}(\mathbf{S}_3) anyons can generate magic states, thereby establishing their universality for quantum computation. Furthermore, we show that the entire scheme can be encoded in just two qudits, offering a compact blueprint that is inherently scalable and readily implementable in current quantum platforms.
