Generalized monogamy relations of concurrence for N -qubit systems
Xue‐Na Zhu, Shao-Ming Fei · Physical Review A · 2015
We present a different kind of monogamous relations based on concurrence and concurrence of assistance. For $N$-qubit systems $AB{C}_{1}...{C}_{N\ensuremath{-}2}$, the monogamy relations satisfied by the concurrence of $N$-qubit pure states under the partition $AB$ and ${C}_{1}...{C}_{N\ensuremath{-}2}$, as well as under the partition $AB{C}_{1}$ and ${C}_{2}...{C}_{N\ensuremath{-}2}$, are established, which gives rise to a kind of restrictions on the entanglement distribution and trade off among the subsystems.
