PASSIVE DECOY STATE QUANTUM KEY DISTRIBUTION WITH FINITE RESOURCE
Yong-Gang Tan, Qing-yu Cai
The passive decoy state quantum key distribution (QKD) protocol is practically interesting for its longer transmission distance and convenience on the decoy states choice. In this paper, its unconditional security with finite length of the key bits is guaranteed. And its performances under this practical condition are demonstrated.
