Bounds on entanglement-assisted source-channel coding via the Lovász ϑ number and its variants

Bounds on entanglement-assisted source-channel coding via the Lovász ϑ number and its variants

We study zero-error entanglement-assisted source-channel coding (communication in the presence of side information). Adapting a technique of Beigi, we show that such coding requires existence of a set of vectors satisfying orthogonality conditions related to suitably defined graphs G and H. Such vec...
