title: Quantum key distribution at 1550 nm using a pulse heralded single photon source.
abstract: Quantum key distribution with pulsed heralded single photon source was performed over 40 km of fiber for the first time to our knowledge. QBER was measured to be 4.23% suggesting security against unconditional attack.
