There is an interesting property about multipartite entanglement, called the monogamy of entanglement. The property can be shown by the monogamy inequality, called the Coffman–Kundu–Wootters inequality [Phys. Rev. A 61, 052306 (2000); Coffman–Kundu–WoottersPhys. Rev. Lett. 96, 220503 (2006)], and more explicitly by the monogamy equality in terms of the concurrence and the concurrence of assistance, CA(BC)2=CAB2+(CACa)2, in the three-qubit system. In this paper, we consider the monogamy equality…

The monogamous nature of the Dicke-class of states, the $N$-qubit pure symmetric states with two distinct spinors, is examined, and it is shown that the states with equal distribution of the two spinors have larger tangle when compared to other inequivalent classes with different degeneracy configurations.
