Measurement-device-independent quantum key distribution with source state errors in photon number space
Cong Jiang, Zong-Wen Yu, Xiang-Bin Wang
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 M…
Measurement-device-independent quantum key distribution with source state errors and statistical fluctuation
Cong Jiang, Zong-Wen Yu, Xiang-Bin Wang
We show how to calculate the secure final key rate in the four-intensity decoy-state MDI-QKD protocol with both source errors and statistical fluctuations with a certain failure pr…
Satellite-to-ground quantum key distribution
Sheng-Kai Liao, Wen-Qi Cai, Wei-Yue Liu +31
Quantum key distribution (QKD) uses individual light quanta in quantum superposition states to guarantee unconditional communication security between distant parties. In practice,…
Optomechanical Microwave Quantum Illumination in Weak Coupling Regime
Wen-Juan Yang, Xiang-Bin Wang
We propose to realize microwave quantum illumination in weak coupling regime based on multimode optomechanical systems. In our proposal the multimode together with a frequency-mism…
