Dihedral \(G=D_m\) quantum-double code[1] 

Description

Quantum-double code whose codewords realize \(G=D_m\) topological order associated with a \(2m\)-element dihedral group \(D_m\). Includes the simplest non-Abelian order \(D_3 = S_3\) associated with the permutation group of three objects.

Gates

Universal topological quantum computation possible for certain groups such as \(G=D_3=S_3\) [2,3].

Realizations

Signatures of a phase equivalent to the \(G=D_4\) quantum double detected in a 27-qubit trapped-ion device by Quantinuum [4]. Preparation of ground states and braiding of anyons has also been performed. The phase was realized as a gauged \(G=\mathbb{Z}_3^2\) twisted quantum double [5], which is the same topological order as the \(G=D_4\) quantum double [6,7].

Notes

See [8; Sec. 5.4] for an introduction to this code.The \( \Phi, \Lambda \) Decodoku game is based on the quantum double model for the group \(D_3=S_3\) of permutations on three letters.Popular summary of realization of non-Abelian topological order in Quanta Magazine.

Cousin

  • Abelian TQD stabilizer code — Upon gauging, a Type-III \(\mathbb{Z}_2^3\) TQD realizes the same topological order as the \(G=D_4\) quantum double model [57].
