Web24 de dez. de 2012 · Using the above argument, Leung et al. recently found the first two examples of graphs whose entanglement-assisted capacity exceeds the Shannon capacity.Their graphs are based on the exceptional root systems and , giving a graph on 63 vertices such that and a graph on 157 vertices such that .They also show that their … WebIn the previous lectures, we have defined the Shannon Capacity of a graph, Θ(G). This lecture is concerned with the Shannon Capacity of the disjoint union G + H of two graphs G and H. The union of two graphs is, informally, what you get when you just place one graph next to the other. In 1956, Shannon conjectured [1] that Θ(G + H) = Θ(G ...
