Checkerboard model code[1]
Description
A foliated type-I fracton code defined on a cubic lattice that admits weight-eight \(X\)- and \(Z\)-type stabilizer generators on the eight vertices of each cube in the lattice. A tetrahedral Ising model can be used to obtain the checkerboard model by gauging [2–4,4] its subsystem symmetry [5].
Variants include the twisted checkerboard model [6].
Decoding
Parallelized matching decoder [7].Code Capacity Threshold
Independent \(X,Z\) noise: \(\approx 7.5\%\), higher than 3D surface code and color code [8].Cousins
- X-cube model code— The checkerboard model is equivalent to two copies of the X-cube model via a local constant-depth unitary [9].
- Fracton Floquet code— The ISG of the X-cube Floquet code can be that of the X-cube model code or the checkerboard model code.

The checkerboard model is equivalent to two copies of the X-cube model via a local constant-depth unitary [9]. Hence, it is a foliated type-I fracton code.

The checkerboard model code can be formulated directly as an LP code [10].
