Plaquette Ising code

Plaquette Ising code[1–3]

Alternative names: Right-angle water ice code, Xu-Moore code.

Description

Classical code defined on a cubic lattice in usually two or three dimensions whose parity checks are applied on the four vertices of each square.

Protection

The 2D code has parameters \([L^2,2L-1,L]\) on a square lattice of size \(L\) [4]. The 3D version has been studied in Ref. [5].

Cousins

Rotated surface code— The 2D plaquette Ising model can be thought of as the rotated surface code whose \(X\)-type stabilizer generators have been converted to \(Z\)-type stabilizer generators.
X-cube model code— The 3D plaquette Ising model can be used to obtain the X-cube model by gauging [6–8,8] its subsystem symmetry [9].
Abelian topological code— The 2D plaquette Ising model can be constructed by coupling layers of 1D \(\mathbb{Z}_2\) lattice gauge theory [10]. A field-theoretic description of the 2D plaquette Ising model can be obtained by coupling layers of 1D gauge theory [11].
Two-foliated fracton code— The two-foliated fracton code is a hypergraph product of the repetition code and the plaquette Ising code on a square lattice with periodic boundary conditions [4].
