Generalized monogamy relations of concurrence forN-qubit systems

Abstract

We present a different kind of monogamous relations based on concurrence and concurrence of assistance. For $N$-qubit systems $AB{C}_1...C_{N-2}$, the monogamy relations satisfied by the concurrence of $N$-qubit pure states under the partition $AB$ and $C_1...C_{N-2}$, as well as under the partition $AB{C}_1$ and $C_2...C_{N-2}$, are established, which gives rise to a kind of restrictions on the entanglement distribution and trade off among the subsystems.
