Monogamous nature of symmetric N-qubit states of the W-class: Concurrence and Negativity Tangle
Using Majorana representation of symmetric N-qubit pure states, we have examined the monogamous nature of the family of states with two-distinct spinors, the W-class of states. We have evaluated the N-concurrence tangle and showed that all the states in this family have vanishing concurrence tangle.
