Parametrized entanglement monotone

Entanglement concurrence has been widely used for featuring entanglement in quantum experiments. As an monotone it is related to specific Tsallis entropy. Our goal this paper propose a new parameterized bipartite which named as $q$-concurrence inspired by general We derive analytical lower bound the of any state employing positive partial transposition criterion and realignment criterion, shows interesting relationship strong separability criteria. The characterize isotropic states. Finally, we provide computational method estimate superposing two pure It that superposition operations can at most increase one ebit case states being superposed are bi-orthogonal or one-sided orthogonal. These results reveal series phenomena about entanglement, may be communication information processing.
