Comparing bound entanglement of bell diagonal pairs of qutrits and ququarts
Abstract We compare the classification as entangled or separable of Bell diagonal bipartite qudits with positive partial transposition (PPT) and their properties for different dimensions. For dimension $$d \ge 3$$ d ≥ 3 , a form of entanglement exists that is hard to detect and called bound entangle...
