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. Webtered photon is completely correlated with the energy of the scattered photon by energy and momentum conservation. This relation is usually written as: ∆λ = λ0 −λ = h mc (1−cosθ) …
