Chiral semion subsystem code[1]
Description
Modular-qudit subsystem stabilizer code with qudit dimension \(q=4\) that is characterized by the chiral semion topological phase. Admits a set of geometrically local stabilizer generators on a torus.
Parents
- Subsystem modular-qudit stabilizer code
- Lattice subsystem code
- Abelian topological code — The semion code is a subsystem code characterized by the chiral semion topological phase.
Cousins
- Double-semion stabilizer code — The semion code can be obtained from the double-semion stabilizer code by gauging out the anyon \(\bar{s}\) [1; Fig. 15].
- \(\mathbb{Z}_q^{(1)}\) subsystem code — The semion code can be obtained from the \(\mathbb{Z}_4^{(1)}\) subsystem code by condensing the anyon \(s^2\) [1; Fig. 15].
- Chiral semion Walker-Wang model code — A unitary QCA encoder applied to product state realizes the 3D chiral semion Walker-Wang model code, which in turn admits 2D chiral semion topological order if truncated at one of its surfaces [2,3].
