Comment: Proceedings of the Nobel Symposium 2009, Qubits for future quantum computers, May 2009 in Goteborg, Sweden
Comment: 4 pages, 2 figures, discussion of postselected electron-electron entanglement added
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 Buttiker, we investigate how the dephasing affects the possibility to violate the Bell Inequality and how system parameters can be adjusted for optimal violation.
