    "abstract": "Long-distance Bell-type experiments are presented. The different experimental\nchallenges and their solutions in order to maintain the strong quantum\ncorrelations between energy-time entangled photons over more than 10 km are\nreported and the results analyzed from the point of view of tests of\nfundamental physics as well as from the more applied side of quantum\ncommunication, specially quantum key distribution. Tests using more than one\nanalyzer on each side are also presented.",
