Fracton Floquet code[1]
Description
3D Floquet code whose qubits are placed on vertices of a truncated cubic honeycomb. Its weight-two check operators are placed on edges of each truncated cube, while weight-three check operators are placed on each triangle. Its ISG can be that of the X-cube model code or the checkerboard model code. On a three-torus of size \(L_x \times L_y \times L_z\), the code consists of \(n= 48L_xL_yL_z\) physical qubits and encodes \(k= 2(L_x+L_y+L_z)-6\) logical qubits.Decoding

- X-cube model code— The ISG of the Fracton Floquet code can be that of the X-cube model code or the checkerboard model code.
- Checkerboard model code— The ISG of the Fracton Floquet code can be that of the X-cube model code or the checkerboard model code.
- Floquet color code— The fracton Floquet code is obtained via a 3D generalization of the construction used in the Floquet color code [1].
