%0 Journal Article %T Violation of Bell's Inequality with Photons from Independent Sources %A T. B. Pittman %A J. D. Franson %J Physics %D 2003 %I arXiv %R 10.1103/PhysRevLett.90.240401 %X We report a violation of Bell's inequality using one photon from a parametric down-conversion source and a second photon from an attenuated laser beam. The two photons were entangled at a beam splitter using the post-selection technique of Shih and Alley [Phys. Rev. Lett. 61, 2921 (1988)]. A quantum interference pattern with a visibility of 91% was obtained using the photons from these independent sources, as compared with a visibility of 99.4% using two photons from a central parametric down-conversion source. %U http://arxiv.org/abs/quant-ph/0301169v2
