Efficient heralding of passively spatial-multiplexed o-band photons for noise-tolerant quantum key distribution

We demonstrate an O-band passively spatial-multiplexed heralded photon source with 74.5% heralding efficiency for noise-tolerant quantum key distribution. Relation between QBER and noise-degraded g(2)(0) of heralded photons transmitted over a 10-km-long fiber is observed.
