Abstract

Twin-Field(TF) quantum key distribution(QKD) is attracting attention due to the possibility of implementing long-range QKD. However, due to the finite-size effect, the secret key rate becomes relatively low. The statistical fluctuation analysis of the four-intensity decoy-state asymmetric TF-QKD system is considered in this study, and optimized parameters for the Gaussian approximation method are also presented.
