Description
A code whose codewords form the ground-state or low-energy subspace of a code Hamiltonian realizing symmetry-protected topological (SPT) order.
Protection
SPT codes typically do not offer protection against generic errors, but can protect against noise that respects the underlying symmetry.
Encoding
Conjectured QCA encoder for SPTs defined by Stiefel-Whitney classes in arbitrary dimensions [3].
Notes
Review on generalized (i.e., non-tensor-product) symmetries [4].
Parent
- Topological code — SPT codes realize symmetry-protected topological phases.
Cousins
- Binary code — SPT orders may be used for encoding classical information [5].
- Twisted quantum double (TQD) code — A TQD code Hamiltonian can be obtained from a 2D particular SPT model by promoting the model's background gauge field to a dynamical gauge field. The same group and cocycle data classifies both 2D SPTs and TQDs [6,7].
- Symmetry-protected self-correcting quantum code — Symmetry-protected self-correcting quantum codes can realize symmetry-protected topological phases [8]. Metastable subspaces of certain many-body Lindbladians can arise due to symmetry relations in the low-lying excitations [9].
- Lattice stabilizer code — Lattice CSS codes in \(D\) dimensions can be converted in SPT Hamiltonians in one less dimension [10].
- Cluster-state code — States realizing various SPT phases are universal resources for MBQC [7,11–17]. A cluster-like state, or a state that is in the same SPT phase as a cluster state, can be prepared in finite time [18].
- 3D color code — Transversal action of \(T\) gates on color codes on general 3-manifolds realizes a \(CCZ\) gate on three logical qubits and is related to a topological invariant that is called the triple intersection number [19]. Transversal \(S\) gate on color codes on general 3-manifolds corresponds to a higher-form symmetry [19].
- Chen-Hsin invertible-order code — Instances of the Chen-Hsin invertible-order code realize beyond-group-cohomology SPTs [20].
- Three-fermion (3F) Walker-Wang model code — The 3F QCA encoder [21,22] can be extended to SPTs in higher dimensions based on an exact bosonization duality [3].
- 3D subsystem color code — Different stabilizer Hamiltonians of the 3D subsystem color code correspond to different SPTs, one of which describes the RBH model [10].
- Fracton stabilizer code — CSS fracton codes can be converted in 2D fractal-like SPT Hamiltonians [10].
- Magnon code — Magnon codewords [23] are associated with 1D SPT orders [24–27].
- Valence-bond-solid (VBS) code — VBS codewords [28] are associated with 1D SPT orders [24–27].
