Abstract

The electron-exchange and shielding on the entanglement fidelity for the elastic electron-ion collision is investigated in strong quantum recoil semiconductor plasmas. The effective Shukla-Eliasson potential and the partial wave method are employed to obtain the collisional entanglement fidelity as a function of the electron-exchange parameter, collision energy, Fermi energy, and plasmon energy. The result shows that the influence of electron-exchange suppresses the transmission of quantum information in strong quantum recoil semiconductor plasmas. It is also found that the collisional entanglement fidelity decreases with an increase of the Fermi energy. Additionally, the collisional entanglement fidelity increases with increasing plasmon energy.
