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: \(\sim 7.5\%\), higher than 3D surface code and color code [4].

Parents

Cousin

  • X-cube model code — The checkerboard model is equivalent to two copies of the X-cube model via a local unitary [5].
