Abstract
Entanglement R\'enyi- entropy is an entanglement measure. It generalizes the entanglement of formation, and they coincide when tends to 1. We derive analytical lower and upper bounds for the entanglement R\'enyi- 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 R\'enyi- entropy and some other entanglement measures.
