Three-fermion (3F) subsystem code[1,2] 

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 two-body interactions [1,5]. All are expected to be equivalent to each other under local Clifford transformations.

  • 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) model code — The 3F model cluster-like state encodes the temporal gate operations on the 3F subsystem code into a third spatial dimension [6]. In addition, one of possible 2D boundaries of the 3F model code is effectively a 2D 3F subsystem code.
