Bell's inequality test with time-delayed two-particle correlations

Adopting the frame of mesoscopic physics, we describe a Bell-type experiment involving time-delayed two-particle correlation measurements. The indistinguishability of quantum particles results in a specific interference between different trajectories; the nonlocality in the time-delayed correlations manifests itself in the violation of a Bell inequality, with the degree of violation related to the accuracy of the measurement. In addition, we demonstrate how the interrelation between the orbital- and the spin-exchange symmetry can by exploited to infer knowledge on spin entanglement from a measurement of orbital entanglement.
