摘要
Reference-frame-independent quantum key distribution(RFI-QKD)has been proven to be very useful and practical under realistic environment.Here,we present a scheme for one-decoy state RFI-QKD based on the work of Rusca et al.[Appl.Phys.Lett.112,171104(2018)],and carry out investigation on its performance under realistic experimental conditions.Numerical simulation results show that the one-decoy state RFI-QKD can achieve comparable performance in terms of secret key rate and transmission distance as the two-decoy state correspondence under practical experimental conditions.On contrast,it does not need to prepare the vacuum state in the former case,substantially reducing the experimental complexity and random number consumptions.Therefore,our present proposal seems very promising in practical implementations of RFI-QKD.
