Compass Codes

The compass model of condensed-matter physics directly inspired the Bacon-Shor subsystem code, but both the Shor code and the rotated surface code can be considered as alternate choices for fixing gauge operators. I will discuss our work exploring the space of compass codes on LxL lattices and potential advantages over the surface codes for errors that are anisotropic or inhomogeneous in space. I will then focus on distance 3 versions of the compass code and describe their possible implementation with trapped atomic ions. This will include a discussion of stabilizer slicing for correcting systematic errors during syndrome extraction.
