Abstract

We give a presentation by generators and relations of the group U4(Z[1/2,i])U_4(\mathbb{Z}[1/\sqrt{2},i]) of unitary 4×44\times 4 matrices with entries in the ring Z[1/2,i]\mathbb{Z}[1/\sqrt{2},i]. This is motivated by the problem of exact synthesis for the Clifford+T gate set in quantum computation.
