From: Cascaded Kerr photon-blockade sources and applications in quantum key distribution
(a) Key rates of decoy state BB84 protocol with different sources: cascaded photon-blockade source (CPBS), the photon-blockade source without a cascade (PBS)19 and WCS. (b) The relative value of the key rates between chosen sources and the perfect single-photon source (PSPS).
