Orbital Entanglement and Violation of Bell Inequalities in the Presence of Dephasing

Authors: P. SAMUELSSON, EUGENE SUKHORUKOV, MARKUS BÜTTIKER

Abstract: We discuss orbital entanglement in mesoscopic conductors, focusing on the effect of dephasing. The entanglement is detected via violation of a Bell Inequality formulated in terms of zero-frequency current correlations. Following closely the recent work by Samuelsson, Sukhorukov and Büttiker [1], we investigate how the dephasing affects the possibility to violate the Bell Inequality and how system parameters can be adjusted for optimal violation.
