Category-based quantum code

Root code for the Category Kingdom

Description

Encodes a finite-dimensional logical Hilbert space into a physical Hilbert space associated with a category. The categories of interest are typically fusion categories, which subsume all finite groups and many state spaces associated with topological codes. Codes on modular fusion categories are often associated with a particular topological quantum field theory (TQFT), as the data of such theories is described by such categories.

Finite-group-based quantum codes, whose basis states are parameterized by a finite group, correspond to category-based codes for the fusion category \(Vec G\). Extensions of such categories to Lie groups can also be done [2–5] (see also [6]).
