Zusammenfassung

We consider the production of spatially separated entangled electrons in transport between a superconductor and ferromagnets: Spin singlet Cooper pairs are filtered into different leads by spin dependent tunneling. We find the full counting statistics depending on the magnetizations and identify the probabilities for productions of entangled electrons taking into account the superconducting proximity effect. Positive contribution to cross correlations are due to coherent transport of two electrons from the superconductor and negative contribution caused by Fermi statistics. We finally show the conditions for a violation of a Bell inequality as experimental test of entanglement.
