Entanglement concurrence has been widely used for featuring entanglement in quantum experiments. As an entanglement monotone it is related to specific quantum Tsallis entropy. Our goal in this paper is to propose a new parameterized bipartite entanglement monotone which is named as q-concurrence inspired by general Tsallis entropy. We derive an analytical lower bound for the q-concurrence of any bipartite quantum entanglement state by employing positive partial transposition criterion andarXiv:2101.04256v1 fatcat:cls5pvflhrbcndovhslmww442e
