Description
2D subsystem stabilizer code whose low-energy excitations realize the three-fermion anyon theory [1,3,4]. One version uses two qubits at each site [2], while other manifestations utilize a single qubit per site and only weight-two (two-body) interactions [1,5]. All are expected to be equivalent to each other via a local constant-depth Clifford circuit.
Parents
- Subsystem qubit stabilizer code
- Lattice subsystem code
- Abelian topological code — The 3F code is a 2D subsystem code characterized by 3F topological order [2], which is chiral and modular.
Cousins
- Kitaev surface code — One version of the 3F subsystem code can be obtained from two copies of the square-lattice surface code by gauging out the anyons \(e_1m_1e_2\) and \(e_2m_2\) [2; Sec. 7.4].
- Three-fermion (3F) Walker-Wang model code — The (three-dimensional) 3F Walker-Wang model cluster-like state encodes the temporal gate operations on the (two-dimensional) 3F subsystem code into a third spatial dimension [6].
- 2D color code — The 2D color code is equivalent to two decoupled copies of the 3F code in the sense that the same anyon theory describes the low-energy excitations of both codes [8][7; Appx. B].
- XYZ ruby Floquet code — Together, all ISGs of the XYZ ruby Floquet code generate the gauge group of the 3F subsystem code.
