@article{Jin2019GeneralizedEM, title={Generalized Entanglement Monogamy and Polygamy Relations for N-Qubit Systems}, author={Zhi-Xiang Jin and S. M. Fei and Xianqing Li-Jost}, journal={International Journal of Theoretical Physics}, year={2019}, volume={58}, pages={1576-1589} }

We investigate the generalized monogamy and polygamy relations N-qubit systems. We give a general upper bound of the αth (0 ≤ α ≤ 2) power of concurrence for N-qubit states. The monogamy relations satisfied by the αth (0 ≤ α ≤ 2) power of concurrence are presented for N-qubit pure states under the partition AB and C1...CN− 2, as well as under the partition ABC1 and C2⋯CN− 2. These inequalities give rise to the restrictions on entanglement distribution and the trade off of entanglement among the…
