We survey some recent results from [BrCo16b], where a class of highly entangled subspaces of bipartite quantum systems is described, which arises from unitary fiber functors on the Temperley-Lieb category associated to the representation theory of free orthogonal quantum groups. By exploiting the rich structure of the Temperley-Lieb category and this particular fiber functor, we are able to precisely determine the largest singular values for these subspaces and obtain lower bounds for the minimum output entropy of the corresponding quantum channels. Future research directions and some open problems are also discussed.
