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.
Variants include the twisted checkerboard model [2].
Decoding
Parallelized matching decoder [3].
Code Capacity Threshold
Independent \(X,Z\) noise: \(\approx 7.5\%\), higher than 3D surface code and color code [4].
Parents
- Qubit CSS code
- Fracton stabilizer code — The checkerboard model is equivalent to two copies of the X-cube model via a local constant-depth unitary [5]. Hence, it is a foliated type-I fracton code.
Cousins
- X-cube model code — The checkerboard model is equivalent to two copies of the X-cube model via a local constant-depth unitary [5].
- 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.
