Cong Jiang, Zong-Wen Yu, and Xiang-Bin Wang
TL;DR
This paper extends the security analysis of measurement-device-independent quantum key distribution by accounting for source state errors, providing a more realistic model that only requires a few parameters for key rate calculation.
Contribution
It introduces a decoy-state MDI-QKD framework that considers source state errors without assuming perfect control, enhancing practical security.
Findings
Security key rate derived with source errors considered
Framework applicable with minimal source parameter requirements
Improved robustness of MDI-QKD in real-world conditions
Abstract
The existing decoy-state MDI-QKD theory assumes the perfect control of the source states which is a an impossible task for any real setup. In this paper, we study the decoy-state MDI-QKD method with source errors without any presumed conditions and we get the final security key rate only with the range of a few parameters in the source state.
