    "abstract": "We report on theoretical and experimental demonstration of high-efficiency\ncoupling of two-photon entangled states produced in the nonlinear process of\nspontaneous parametric down conversion into a single-mode fiber. We determine\nconstraints for the optimal coupling parameters. This result is crucial for\npractical implementation of quantum key distribution protocols with entangled\nstates.",
