Quantum interference and non-locality of independent photons from disparate sources — •Ralph Wiegner1, Joachim von Zanthier1, and Girish Agarwal2 — 1Institut für Optik, Information und Photonik, Universität Erlangen-Nürnberg, Erlangen, Germany — 2Department of Physics, Oklahoma State University, Stillwater, OK, USA
We quantitatively investigate the non-classicality and non-locality of a whole new class of mixed disparate quantum and semiquantum photon sources at the quantum-classical boundary (arXiv:1005.4176v1). The key quantity in our investigations is the visibility of the corresponding photon-photon correlation function. We present explicit results on the violations of the Cauchy-Schwarz inequality - which is a measure of nonclassicality - as well as of Bell-type inequalities for path correlations rather than for polarization correlations.
