Abelian topological code

Description

Code whose codewords realize topological order associated with an abelian group. Stub.

Any local quantum circuit connecting ground states of topological orders with non-isomorphic abelian groups must have depth that is at least linear in the system’s diameter [1].

  • Clifford-deformed surface code (CDSC) — Local deformations of the surface code preserve its \(\mathbb{Z}_2\) topological order.
  • Color code — When treated as ground states of the code Hamiltonian, 2D color code states on realize \(\mathbb{Z}_2\times\mathbb{Z}_2\) topological order [3], equivalent to the phase realized by two copies of the surface code [4].
  • Double-semion code — When treated as ground states of the code Hamiltonian, the code states realize double-semion topological order, a topological phase of matter that also exists in twisted \(\mathbb{Z}_2\) gauge theory [5].
  • Kitaev surface code — When treated as ground states of the code Hamiltonian, the code states realize \(\mathbb{Z}_2\) topological order, a topological phase of matter that also exists in \(\mathbb{Z}_2\) lattice gauge theory [6]. Codewords correspond to ground state of the code Hamiltonian, and error operators correspond to spontaneous creation and annihilation of pairs of charges or vortices.
  • Matching code — Matching codes were inspired by the Kitaev honeycomb model [7], which realizes \(\mathbb{Z}_2\) topological order.
  • Modular-qudit surface code — Qudit surface code Hamiltonians admit topological phases associated with \(\mathbb{Z}_q\) [8].

Cousins

  • Modular-qudit stabilizer code — All abelian topological orders can be realized as modular-qudit stabilizer codes [2].
  • Translationally-invariant stabilizer code — Translationally-invariant stabilizer codes can realize abelian topological orders. Conversely, abelian topological codes need not be translationally invariant, and can realize multiple topological phases on one lattice.
  • XS stabilizer code — Twisted quantum double models for the groups \(\mathbb{Z}_2^k\) can be realized as XS stabilizer codes.
  • XZZX surface code — Example of \(\mathbb{Z}_2\) topological order in the Wen plaquette model [9].
