Abstract:
We present a new kind of monogamous relations based on concurrence and concurrence of assistance. For N-qubit systems ABC₁...C_N−2, the monogamy relations satisfied by the concurrence of N-qubit pure states under the partition AB and C₁...C_N−2, as well as under the partition ABC₁ and C₂...C_N−2 are established, which give rise to a kind of restrictions on the entanglement distribution and trade off among the subsystems.
