Monogamy properties of qubit systems
Abstract
We investigate monogamy relations related to quantum entanglement for n-qubit quantum systems. General monogamy inequalities are presented to the βth (β∈(0,2)) power of concurrence, negativity and the convex-roof extended negativity, as well as the βth (β∈(0,2)) power of entanglement of formation. These monogamy relations are complementary to the existing ones with different regions of parameter β. In additions, new monogamy relations are also derived which include the existing ones as special cases.
