Abstract

As part of a protocol, we braid in a certain way six anyons of topological charges 222211222211 in the Kauffman-Jones version of SU(2)SU(2) Chern-Simons theory at level 44. The gate we obtain is a braid for the usual qutrit 22222222 but with respect to a different basis. With respect to that basis, the Freedman group of \cite{LEV} is identical to the DD-group D(18,1,1;2,1,1)D(18,1,1;2,1,1). We give a physical interpretation for each Blichfeld generator of the group D(18,1,1;2,1,1)D(18,1,1;2,1,1). Inspired by these new techniques for the qutrit, we are able to make new ancillas, namely 12(1>+3>)\frac{1}{\sqrt{2}}(|1>\,+|3>) and 12(1>3>)\frac{1}{\sqrt{2}}(|1>\,-|3>), for the qubit 12211221.
