Abstract
|
In this research work, we investigate the quantum correlation of N-qubit symmetric systems in Dicke state |N,M >. The Dicke states are eigenfunction of S2 and Sz and S2 and Sz are collective operators of the system. Due to the symmetry, the state of the system under the exchange of any two-qubit will not change. Then we choose an arbitrary two-qubit and represent the density matrix of them in terms of collective operators of system. We compute the quantum correlation via direct measure for two-qubit in terms of parameters N and M and in final we compare the obtained results.
