Two-gauge theory code[1]
Also known as Higher gauge theory code.
Description
A code whose codewords realize lattice two-gauge theory [2–7] for a finite two-group (a.k.a. a crossed module) in arbitrary spatial dimension. There exist several lattice-model formulations in arbitrary spatial dimension [1,8] as well as explicitly in 3D [9–12] and 4D [12], with the 3D case realizing the Yetter model [13–16].
A two-gauge theory generalizes ordinary gauge theory by replacing the gauge group with a two-group. Lattice formulations place gauge fields not only on edges of a lattice (as they do in ordinary gauge theory), but also on higher-dimensional structures such as faces.
Ground-state degeneracy is a topological invariant in the 3D case [8]. Excitations of the 3D models are studied in Refs. [17–19]. Generalizations of Ocneanu's tube algebras [20,21] can be used to characterize excitations [17,22].
Parents
- Category-based quantum code
- Commuting-projector Hamiltonian code — Two-gauge theory codewords form ground-state subspaces of frustration-free commuting projector Hamiltonians.
- Frustration-free Hamiltonian code — Two-gauge theory codewords form ground-state subspaces of frustration-free commuting projector Hamiltonians.
- Topological code — Two-gauge theory codes realize lattice two-gauge theory for a finite two-group.
Children
- Dijkgraaf-Witten gauge theory code — Replacing the two-group data in a two-gauge theory with a group and a cocycle reproduces the phase of the Dijkgraaf-Witten gauge theory, with the two theories equivalent in 2D [1]. Generalizations of Ocneanu's tube algebras [20,21] can be used to characterize excitations in both theories [17; Sec. 4.2]. A Dijkgraaf-Witten Lagrangian can also be re-expressed as a two-group gauge theory Lagrangian by relating the electric and magnetic gauge fields via the equations of motion [1,23,24].
- Cubic theory code — Cubic theory codes realize higher-form \(\mathbb{Z}_2^3\) gauge theories with non-Abelian excitations in arbitrary dimensions.
- Chen-Hsin invertible-order code — Chen-Hsin invertible-order codes realize beyond-group-cohomology invertible topological phases of order two and four in arbitrary dimensions. These phases are described by invertible two-gauge theories [25; pg. 11].
Cousins
- \(G\)-enriched Walker-Wang model code — \(G\)-enriched Walker-Wang models realize 3D two-gauge theories [26].
- Walker-Wang model code — Two-gauge theory codes for particular two-groups are dual to certain Walker-Wang models based on Abelian groups [9; Sec. V][11; Sec. 7].
- Quantum-double code — Restricting 2-gauge theory constructions to a 2D manifold and replacing the 2-group with a group reproduces the phase of the Kitaev quantum double model [9].
- 3D subsystem color code — The 3D subsystem color code can be ungauged [27–29,29] to obtain six copies of \(\mathbb{Z}_2\) gauge theory with one-form symmetries [30].
