Description
A non-CSS QLDPC code constructed from three classical codes. The construction of an XYZ product code is similar to that of a hypergraph product code and related codes. The idea is that rather than taking a product of only two classical codes to produce a CSS code, a third classical code is considered, acting with Pauli-\(Y\) operators.
Rate
Not much has been proven about the relationship between XYZ product codes and other codes. The logical dimension depends on properties of the input classical codes, specifically similarity invariants from abstract algebra. It is conjectured that specific instances of XYZ product codes have a constant encoding rate and a minimum distance of \(d \in \Theta(n^{2/3})\) [2].

Children
- Chamon model code — The Chamon model code can be obtained from a hypergraph product of three repetition codes [1], but done in a different way than the 3D surface code; see [2; Sec. 3.4].
- 3D surface code — The 3D planar (3D toric) code can be obtained from a hypergraph product of three repetition (cyclic) codes [4; Exam. A.1], but done in a different way than the Chamon code; see [2; Sec. 3.4].
Cousin
- Hypergraph product (HGP) code — Hypergraph (XYZ) product codes are constructed out of hypergraph products of two (three) classical linear codes.
