Influence of the ion wake-field on the collisional entanglement fidelity in complex dusty plasmas

Abstract

The ion wake-field effects on the entanglement fidelity for the elastic electron-dust grain collisions are investigated in complex dusty plasmas. The screened effective potential and partial wave analysis are employed to obtain the entanglement fidelity in dusty plasmas as a function of the Mach number, Debye length, and collision energy. It is shown that the ion wake-field effect suppresses the entanglement fidelity in dusty plasmas. It is also found that the ion wake-field effect on the entanglement fidelity decreases with an increase of the collision energy. (C) 2012 American Institute of Physics.
