Universal topological quantum computing via double-braiding in SU(2) Witten–Chern–Simons theory
We study the problem of universality in the anyon model described by the SU(2) Witten–Chern–Simons theory at level k. A classic theorem of Freedman–Larsen–Wang states that for \(k \ge 3, \ k \ne 4\), braiding of the anyons of topological charge 1/2 is universal for topological quantum computing. For the case of one qubit, we prove a stronger result that double-braiding of such anyons alone is already universal.
