Lower and upper bounds for entanglement of Rényi-α entropy
Wei Song, Lin Chen, Zhuo-Liang Cao · Scientific Reports · 2016
Entanglement Rényi-α entropy is an entanglement measure. It reduces to the standard entanglement of formation when α tends to 1. We derive analytical lower and upper bounds for the entanglement Rényi-α entropy of arbitrary dimensional bipartite quantum systems. We also demonstrate the application our bound for some concrete examples. Moreover, we establish the relation between entanglement Rényi-α entropy and some other entanglement measures.
