Hamiltonian-based code whose Hamiltonian terms can be expressed as projectors (i.e., having eigenvalues 0 or 1) that commute with each other.
- Multi-fusion string-net code
- Quantum locally testable code (QLTC) — Quantum LTC codespaces are ground-state spaces of \(u\)-local commuting-projector Hamiltonians.
- Stabilizer code — Codespace is the ground-state space of the code Hamiltonian, which consists of an equal linear combination of stabilizer generators and which can be made into a commuting-projector Hamiltonian.
