Non-commutative symmetry groups have been so far represented by non-commutative matrices, i.e., matrices in which the order of operations influences the end result.

This is a non-commutative, and thus quantum, generalization of a magic square. The authors show that quantum magic squares cannot be as easily characterized as their "classical" cousins.
