Bigalois extensions and the graph isomorphism game
Michael Brannan, Alexandru Chirvasitu, Kari Eifler +4
We study the graph isomorphism game that arises in quantum information theory from the perspective of bigalois extensions of compact quantum groups. We show that every algebraic qu…
Schur multipliers and mixed unitary maps
Samuel J. Harris, Rupert H. Levene, Vern I. Paulsen +2
We consider the tensor product of the completely depolarising channel on matrices with the map of Schur multiplication by a correlation matrix and characte…
Bipartite matrix-valued tensor product correlations that are not finitely representable
Samuel J. Harris
We consider the matrix-valued generalizations of bipartite tensor product quantum correlations and bipartite infinite-dimensional tensor product quantum correlations, respectively.…
Crossed products of operator systems
Samuel J. Harris, Se-Jin Kim
In this paper we introduce the crossed product construction for a discrete group action on an operator system. In analogy to the work of E. Katsoulis and C. Ramsey, we describe thr…
