    "abstract": "Propagation of entangled photons in optical fiber is one of the fundamental\nissues for realizing quantum communication protocols. When entanglement in\npolarization is considered, arises the problem of compensating for the fiber\neffect on photons polarization. In this paper we demonstrate an effective\nsolution where a Faraday mirror allows to cancel undesired effects of\npolarization drift in fiber. This technique is applied to a protocol for\ngenerating Bell states by a narrow temporal selection of the second-order\nintensity correlation function.",
