    "abstract": "We report a violation of Bell\u0027s inequality using one photon from a parametric\ndown-conversion source and a second photon from an attenuated laser beam. The\ntwo photons were entangled at a beam splitter using the post-selection\ntechnique of Shih and Alley [Phys. Rev. Lett. 61, 2921 (1988)]. A quantum\ninterference pattern with a visibility of 91% was obtained using the photons\nfrom these independent sources, as compared with a visibility of 99.4% using\ntwo photons from a central parametric down-conversion source.",
