# Entanglement and quantum combinatorial designs

We introduce the notion of quantum orthogonal arrays as a generalization of orthogonal arrays. These quantum combinatorial designs naturally induce the concepts of quantum Latin squares, cubes, hypercubes and a notion of orthogonality between them. Furthermore, quantum orthogonal arrays are one-to-one related to $k$-uniform states, i.e., pure states such that every reduction to $k$ parties is maximally mixed. We derive quantum orthogonal arrays having an arbitrary large number of columns and…
