Multi-fusion string-net code[1]
Description
Family of codes resulting from the string-net construction but whose input is a unitary multi-fusion category (as opposed to a unitary fusion category).
Parents
- Category-based quantum code
- Topological code — Enriched string-net codes realize 2D topological phases based on unitary multi-fusion categories.
- Commuting-projector Hamiltonian code — Multi-fusion string-net codes form eigenspaces of frustration-free commuting projector Hamiltonians.
- Frustration-free Hamiltonian code — Multi-fusion string-net codes form eigenspaces of frustration-free commuting projector Hamiltonians.
Children
- Groupoid toric code — Groupoid toric-code categories are unitary multi-fusion categories based on matrix algebras [1], so groupoid toric codes can equivalently be formulated as multi-fusion string-net codes.
- String-net code
Cousin
- Hopf-algebra quantum-double code — Extending the Hopf algebra quantum-double construction to a weak Hopf algebra construction yields an alternative formulation [3][2; Fig. 1] for realizing multi-fusion string-net topological orders because of the relationship between representations of weak Hopf algebras and multi-fusion categories [4]. Tensor network constructions can be done for either formulation [5,6].
