WebApr 27, 2024 · Abstract. Reference-frame-independent quantum key distribution (RFI-QKD) can generate secret keys in the presence of unknown and slowly drifting reference frames. Due to the unavoidable multiphoton events in practical weak coherent states (WCS), the decoy-state method is adopted to combat the potential photon-number-splitting attacks. Webthen reduces the after-pulse noise of the detector. At a repetition rate of 200 MHz, the after-pulse probability is 8.2% less than conventional gating signal detection. ... cially the quantum key distribution(QKD) based on optical fiber links, the telecommunication wavelength of 1.55 m is the most desirable for long-distance transmission, since ...
