Abstract

Quantum relative entropy has been studied extensively, and many forms have been derived due to different parameters. Maximum relative entropy and minimum relative entropy are obtained by taking specific conditions for parameters. Our goal in this paper is to propose a new bipartite entanglement monotone based on minimum relative entropy of any bipartite quantum entanglement state. We also demonstrate that entanglement monotone satisfies some basic properties as an entanglement measure.
