  • Abstract
    Hwang (2003) has proposed a decoy state method in quantum key distribution (QKD). In Hwang´s proposal, the average photon number of the decoy state is about two. This paper propose a new decoy state scheme using vacua or very weak coherent states as decoy states and discuss its advantages.
