# Tighter entanglement monogamy relations of qubit systems

Tighter entanglement monogamy relations of qubit systems Monogamy relations characterize the distributions of entanglement in multipartite systems. We investigate monogamy relations related to the concurrence C and the entanglement of formation E. We present new entanglement monogamy relations satisfied by the $$\alpha$$ α -th power of concurrence for all $$\alpha \ge 2$$ α ≥ 2 , and the $$\alpha$$ α -th power of the entanglement of formation for all $$\alpha \ge \sqrt{2}$$ α ≥ 2 . These monogamy relations are shown to be tighter than the existing ones. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals

### Abstract

Monogamy relations characterize the distributions of entanglement in multipartite systems. We investigate monogamy relations related to the concurrence C and the entanglement of formation E. We present new entanglement monogamy relations satisfied by the $$\alpha$$ α -th power of concurrence for all $$\alpha \ge 2$$ α ≥ 2 , and the $$\alpha$$ α -th power of the entanglement of formation for all $$\alpha \ge \sqrt{2}$$ α ≥ 2 . These monogamy relations are shown to be tighter than the existing ones.
