Performance of photon-pair quantum key distribution systems

We analyse the quantitative improvement in performance provided by a novel quantum key distribution (QKD) system that employs a correlated photon source (CPS) and a photon-number resolving detector (PNR). Calculations suggest that given current technology, the CPS/PNR implementation offers an improvement of several orders of magnitude in secure bit rate over previously described implementations.

Quantum key distribution with mode-locked two-photon states

Tomoyuki Horikiri

Quantum key distribution (QKD) with mode-locked two-photon states is discussed. The photon source with a comb-like second-order correlation function is shown to be useful for implementing long distance time-energy entanglement QKD.

Realistic and general model for quantum key distribution with entangled-photon sources

Zhen-Qiu Zhong, Shuang Wang, Xiao-Hai Zhan +4 more

Entanglement-based quantum key distribution (EB-QKD) has several advantages over prepare-and-measure protocols, such as eliminating the need for decoy states and active modulators. At present, entanglement sources based on the spontaneous parametric down-conversion process have been widely used in EB-QKD experiments. Most of the existing models regard the photon-number distribution of pulse-pumped entanglement sources as thermal. However, doing so ignores any effects of spectral modes, which will lead to the overestimation of the secure key rate. In this paper, we analyze the correlation between the photon-number distribution and the joint spectral distribution and rewrite the quantum state of the photon pairs. Then we apply the results to EB-QKD and present a general model which can be used to calculate the secure key rate not only for any pulse-pumped systems but even for cw-pumped systems.
