    "abstract": "We present an experiment testing quantum correlations with frequency shifted\nphotons. We test Bell inequality with 2-photon interferometry where we replace\nthe beamsplitters by acousto-optic modulators, which are equivalent to moving\nbeamsplitters. We measure the 2-photon beatings induced by the frequency\nshifts, and we propose a cryptographic scheme in relation. Finally, setting the\nexperiment in a relativistic configuration, we demonstrate that the quantum\ncorrelations are not only independent of the distance but also of the time\nordering between the two single-photon measurements.",
