Bell's inequality test with time-delayed two-particle correlations
arXiv:0706.3437 · doi:10.1103/PhysRevB.77.035301
Abstract
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. We show how the non-locality in the time-delayed correlations due to the indistinguishability of the quantum particles manifests itself in the violation of a Bell inequality, where the degree of violation is related to the accuracy of the measurement. 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.
