Entanglement of spin coherent mixed states
Mostafa Mansour, Y. Hassouni · International Journal of Quantum Information · 2016
In this paper, we quantify the amount of entanglement of bipartite mixed states represented by a statistical mixture of the more general type of two-qubit non-orthogonal states of the form: [Formula: see text], constructed by linearly independent spin coherent states. We use the concurrence as a measure of entanglement and we study its behavior in terms of the amplitudes of SU(2) coherent states.
