Collective and Screening Effects on Entanglement Fidelity in Elastic Collisions in Nonideal Plasmas

The nonideal collective and plasma screening effects on the entanglement fidelity in elastic collisions are investigated in classical nonideal plasmas. The entanglement fidelity in nonideal plasmas is obtained as a function of the non ideality plasma parameter, Debye length, and collision energy. It is found that the plasma screening effect significantly increases the entanglement fidelity, especially for low collision energies.The entanglement fidelity is found to decrease with increasing collision energy. It is also found that the collective effect enhances the entanglement fidelity in nonideal plasmas
