Lattice-based code
Description
Encodes states (codewords) in coordinates of a lattice in the \(n\)-dimensional real coordinate space \(\mathbb{R}^n\). The number of codewords may be infinite because the coordinate space is infinite-dimensional, so various restricted versions have to be constructed in practice. Since lattices are closed under addition, lattice-based codes can be thought of as linear codes over the reals.
Parent
- Error-correcting code (ECC) — Error-correcting codes are defined for a finite alphabet, so only finite lattice-based codes are children.
Cousins
- Linear binary code — Since lattices are closed under addition, lattice-based codes can be thought of as linear codes over the reals.
- Group-based code — Group-based codes whose alphabet is based on the group \(\mathbb{R}\) are lattice-based codes.
- Multi-mode GKP code — Multimode GKP codes are quantum analogues of lattice-based codes.
