A set of multipartite orthogonal product states is strongly nonlocal if it locally irreducible in every bipartition, which shows the phenomenon strong quantum nonlocality without entanglement. It known that unextendible bases (UPBs) can show Thus interesting to investigate for UPBs. Most UPBs with minimum size cannot demonstrate nonlocality. In this paper, we construct a series different large ...

The strong product on graphs is also called the normal or AND product. It union of Cartesian and tensor product, a binary operation graphs. This takes two produces new graph. In this paper, we will study weighted key to relationship between spectrum original that their graph provide reasonable weight function We introduce definition <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML"...
