Description
A 3D lattice stabilizer code whose low-energy excitations on boundaries realize a 3D time-reversal SPT order [1] and that can be used as a resource state for fault-tolerant MBQC [2]. The anyons at the boundary of the lattice are described by the 3F anyon theory.
Encoding
3F QCA encoder [3,4], which can be simplified using bosonization [5] and can be extended to SPTs in higher dimensions based on an exact bosonization duality [6].
Gates
Clifford gates can be performed by braiding and fusing symmetry defects in the MBQC model.
Fault Tolerance
Fault-tolerant MBQC protocol by encoding in, braiding, and fusing symmetry defects.

- Qubit stabilizer code
- 3D lattice stabilizer code
- Walker-Wang model code — The Walker-Wang model code reduces to the 3F model code when the input category \(\mathcal{C}=3F\) [2]. When treated as ground states of the code Hamiltonian, 3F Walker-Wang model code states realize a 3D time-reversal SPT order [1]. The anyons at the boundary of the lattice are described by the 3F anyon theory.
- Symmetry-protected topological (SPT) code — When treated as ground states of the code Hamiltonian, 3F Walker-Wang model code states realize a 3D time-reversal SPT order [1]. The 3F Walker-Wang QCA encoder [3,4] can be extended to SPTs in higher dimensions based on an exact bosonization duality [6].
