Pa. Hiskett et al., Eighty kilometre transmission experiment using an InGaAs/InP SPAD-based quantum cryptography receiver operating at 1.55 mu m, J MOD OPT, 48(13), 2001, pp. 1957-1966
A polarization-based receiver for quantum key distribution incorporating an
InGaAs/InP single photon avalanche photodiode (SPAD) has been constructed
to investigate the potential for increasing the transmission distance in lo
ng wavelength quantum key distribution systems beyond the 50 km range.
