Landau-level spin code[1]
Description
Approximate quantum code that encodes a qudit in the finite-dimensional Hilbert space of a single spin, i.e., a spherical Landau level. Codewords are approximately orthogonal Landau-level spin coherent states whose orientations are spaced maximally far apart along a great circle (equator) of the sphere. The larger the spin, the better the performance.
Protection
Protects against equatorial rotational errors acting on the overall spin.

- Single-spin code
- Approximate quantum error-correcting code (AQECC) — The Landau-level spin code approximately protects against rotational errors.
Cousin
- Spin GKP code — The spin-GKP (Landau-level) code is a GKP-like encoding in (Landau-level) spin coherent states.
