摘要

We develop monogamy relations of multiqubit quantum entanglement in terms of the concurrence, entanglement of formation, convex-roof extended negativity and Tsallis-q entanglement. These monogamy inequalities are proved to be tighter than the existing ones. The corresponding examples are also presented.
