Group-based cluster-state code[1]
Description
A code based on a group-based cluster state for a finite group \(G\) [1]. Such cluster states can be defined using a graph and conditional group multiplication operations. A group-based cluster state for \(G=GF(q)\) for prime-power \(q\) is called a Galois-qudit cluster state, while the state for \(G=\mathbb{Z}_q\) for positive \(q\) is called a modular-qudit cluster state.
Gates
1D group-based cluster states for certain non-Abelian groups [2] are resources for universal MBQC.
Parents
- Group GKP code — Group-based cluster states are stabilized by group-based error operators [1,2].
- Hopf-algebra cluster-state code — Hopf-algebra cluster-state codes reduce to group-based cluster-state codes when the Hopf algebra reduces to a group.
Child
- Modular-qudit cluster-state code — Group-based cluster-state codes reduce to cluster-state codes for \(G=\mathbb{Z}_q\).
Cousins
- Graph quantum code — A graph quantum code for Abelian \(G\) reduces to a group-based cluster state when its logical dimension is one [3].
- Analog-cluster-state code — Analog cluster states are group-based cluster states for \(G=\mathbb{R}\), a non-finite group.
- Galois-qudit CWS code — A single Galois-qudit cluster state is used to construct a modular-qudit CWS code.
