Creating path entanglement and violating Bell inequalities by independent photon sources

arXiv:1001.3830 · doi:10.1016/j.physleta.2010.06.047

Abstract

We demonstrate a novel approach of violating position dependent Bell inequalities by photons emitted via independent photon sources in free space. We trace this violation back to path entanglement created a posteriori by the selection of modes due to the process of detection.
