200km Decoy-state quantum key distribution with photon polarization
Teng-Yun Chen, Jian Wang, Yang Liu +10
We demonstrate the decoy-state quantum key distribution over 200 km with photon polarization through optical fiber, by using super-conducting single photon detector with a repetiti…

Decoy-state quantum key distribution with both source errors and statistical fluctuations
Xiang-Bin Wang, Lin Yang, Cheng-Zhi Peng +1
We show how to calculate the fraction of single photon counts of the 3-intensity decoy-state quantum cryptography faithfully with both statistical fluctuations and source errors. O…

Security of decoy-state quantum key distribution with inexactly controlled source
Xiang-Bin Wang, Cheng-Zhi Peng, Jun Zhang +1
We show the unconditional security of decoy-state method quantum cryptography with whatever intensity error pattern provided that the error is not too large. Our result immediately…
