Quantum effects on the entanglement fidelity in elastic scatterings in strongly coupled semiclassical plasmas

Abstract

The quantum effects on the entanglement fidelity in elastic electron-ion scatterings are investigated in strongly coupled semiclassical plasmas. The screened pseudopotential model and partial wave analysis are employed to obtain the entanglement fidelity in strongly coupled semiclassical plasmas as a function of the thermal de Broglie wavelength, Debye length, and projectile energy. It is shown that the quantum effect significantly enhances the entanglement fidelity in strongly coupled semiclassical plasmas. It is also found that the entanglement fidelity increases with increasing the projectile energy. In addition, it is shown that the plasma screening effect increases the entanglement fidelity slightly. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.2997334]
