Abstract:
Quantum entanglement plays essential roles in quantum information processing. The monogamy and polygamy relations characterize the entanglement distributions in the multipartite systems. We present a class of monogamy inequalities related to the μth power of the entanglement measure based on Rényi-α entropy, as well as polygamy relations in terms of the μth powered of Rényi-α entanglement of assistance. These monogamy and polygamy relations are shown to be tighter than the existing ones.
