Description
A CWS code for Galois qudits, defined using a Galois-qudit cluster state and a set of Galois-qudit \(Z\)-type Pauli strings defined by a \(q\)-ary classical code.
This entry has not yet been developed in the literature, so the formulation below is a conjecture. The Galois-qudit CWS construction takes in \( \mathcal{Q} = (\mathcal{G},\mathcal{C}) \), where \(\mathcal{G}\) is a graph, and where \(\mathcal{C}\) is an \((n,K,d)_q\) \(q\)-ary code. From the graph, we form the Galois-qudit cluster state \( |\mathcal{G} \rangle \). From the \(q\)-ary code, we form Galois-qudit Pauli \(Z\)-type operators \( W_i = Z_{c_{i,1}} \otimes \cdots \otimes Z_{c_{i,n}} \), where \(c_{i,j} \) is the \(j\)-th coordinate of the \(i\)-th classical codeword. The codewords are then \( | i \rangle = W_i | \mathcal{G} \rangle \).
Parent
- Galois-qudit USt code — Any Galois-qudit CWS code can be written as a USt whose (\(K=1\)) stabilizer code is the Galois-qudit cluster state and whose coset representatives are constructed from the \(q\)-ary classical code.
Child
- Codeword stabilized (CWS) code — Galois-qudit CWS codes reduce to CWS codes for \(q=2\).
Cousins
- Group-based cluster-state code — A single Galois-qudit cluster state is used to construct a modular-qudit CWS code.
- Galois-qudit stabilizer code — Galois-qudit CWS codes whose underlying classical code is a linear \(q\)-ary code are Galois-qudit stabilizer codes containing a cluster-state codeword.
