    "abstract": "A pulsed source of energy-time entangled photon pairs pumped by a standard\nlaser diode is proposed and demonstrated. The basic states can be distinguished\nby their time of arrival. This greatly simplifies the realization of 2-photon\nquantum cryptography, Bell state analyzers, quantum teleportation, dense\ncoding, entanglement swapping, GHZ-states sources, etc. Moreover the\nentanglement is well protected during photon propagation in telecom optical\nfibers, opening the door to few-photon applications of quantum communication\nover long distances.",
