Abstract

Chern-Simons topological quantum computer is a device that can be effectively described by the Chern-Simons topological quantum field theory and used for quantum computations. Quantum qudit gates of this quantum computer are represented by sequences of quantum R\mathcal{R}-matrices. Its dimension and explicit form depend on the parameters of the Chern-Simons theory -- level kk, gauge group SU(N)SU(N), and representation, which is chosen to be symmetric representation [r][r]. In this paper, we examine the universality of such a quantum computer. We prove that for sufficiently large kk it is universal, and the minimum allowed value of kk depends on the remaining parameters rr and NN.
