Splet21. feb. 2024 · The shot-noise unit in continuous-variable quantum key distribution plays an important and fundamental role in experimental implementation, as it is used as a normalization parameter that contributes to performing security analyses and distilling key information. However, the traditional calibration procedure and detector model cannot … Spletlevels will be limited by the shot noise and the APD’s leakage current. Shot noise derives from the random statistical Poissonian fluctuations of the dark current, ID (or signal current). Dark current shot noise (IN(SHOT)) is normally given by iN(SHOT) = (2⋅q⋅B⋅ID) ½, for a PIN detector, where B is the system bandwidth.
