A code whose codewords make up the ground-state space of a fracton-phase Hamiltonian.
- Quantum low-density parity-check (QLDPC) code — Fracton codes admit geometrically local stabilizer generators on a cubic lattice.
- Topological code — Fracton phases can be understood as topological defect networks, meaning that they can be described in the language of topological quantum field theory with defects [2,3].
- Groupoid toric code — Some groupiod toric code models admit fracton-like features such as extensive ground-state degeneracy and excitations with restricted mobility.
- Translationally invariant stabilizer code — Translationally-invariant stabilizer codes can realize fracton orders. Conversely, fracton codes need not be translationally invariant, and can realize multiple phases on one lattice.
- XZZX surface code — Subsystem symmetries play a role in finite-bias decoders for both codes .
