Fiber code[1]
Description
Approximate quantum code that encodes a qudit in an induced representation \(\text{Ind}_G^{SO(3)} \Gamma\), induced by the irrep \(\Gamma\) of a subgroup \(G\subset SO(3)\). Such spaces correspond to orientation state spaces of certain symmetric molecules [1], with the base space \(SO(3)/G\) labeling the orientations and the fiber carrying the \(\Gamma\)-irrep encoding the logical information.Protection
A basis of noise operators is developed for general induced representations in Ref. [1].Cousin
- Molecular code— Molecular codes encode quantum information into superpositions of multiple orientations of an asymmetric molecule [2], while fiber codes encode into the fiber associated with a single orientation of certain symmetric molecules [1].

Fiber codes are defined on an induced representation \(\text{Ind}_G^{SO(3)} \Gamma\), induced by the irrep \(\Gamma\) of a subgroup \(G\subset SO(3)\).
