One of the most critical aspects of studying entanglement states is quantifying the degree of entanglement. One of the entanglement measures for pure states is Van- Neumann entropy, which is why Van-Neumann entropy is also called entanglement entropy

In this work, superposition of spin coherent states composed of two qubits is formed and by calculating the geometric measure of mixing of the system introduced in this work, the degree of mixedness of the studied state is investigated. In the follow

Choosing I-concurrence as the measure of bipartite entanglement and using von Neumann projective local measurements, localizable entanglement (LE) in a three-qutrit system is studied. A superposition of the qutrit-coherentstate of this system is cons

Dynamics of localizable entanglement in a qutrit chain, in the presence of the Dzyaloshinskii---Moriya (DM) interaction is studied. Three distinct initial states, namely, superposition of the ground and the first excited state (SGE), a GHZ state and

Using concurrence as a measure of entanglement, we present analytical and numerical study of entanglement dynamics in a two-qutrit system in the presence of the Dzyaloshinskii---Moriya interaction, as a function of the parameters involved. Three dist
